Mitsubishi Pajero 4 air conditioner does not work. Disabling the rear air conditioner on Mitsubishi Pajero

This time we have prepared useful information for car owners Mitsubishi Pajero / Montero 3rd and 4th generation... We want to talk about the main problem that occurs with the air conditioning system on these cars.

As usual, a short introduction. Undoubtedly, air conditioning is a very important indicator of the comfort of a car, especially in the summer season, when the thermometer exceeds the temperature of 30C. For greater comfort in off-road vehicles Mitsubishi Pajero / Montero installed double air conditioning: front and rear. Its main difference is the rear contour. However, after two years of operation, and sometimes even after a year, the air conditioner begins to fail to cope with the cooling functions. Instead of cold air, warm air begins to blow.

A common system malfunction is insufficient refrigerant pressure, or poor cooling. This means that somewhere there is a refrigerant leak, or the cooling radiator is clogged, as a result of which the passage of air for cooling is impeded.
The most common reason for refrigerant leaks lies in the pipes (lines) running under the bottom of the car to the rear air conditioning heater. These lines are secured with steel straps. Due to the winter operation of the car on our roads, reagents and road dirt corrode these silumin tubes, which leads to a malfunction of the air conditioner. The second reason lies in the rear evaporator, which is constantly attacked by dirt from the rear wheel and further corrosion.

The constant replacement of silumin pipes is quite an expensive process. We offer a simple solution - turn off the rear air conditioner using plugs and get rid of the problem forever. Installation cost plugs in our Mitsubishi Motors Club car service with the work and filling of oil and refrigerant into the air conditioner system is only 5 900 rub.

For comparison, we indicate cost of work when replacing pipes:
Replacing the rear low pressure air conditioner with oil and refrigerant charging into the air conditioning system - Replacement cost - 12,000 rubles
The cost of replacing the rear high-pressure air conditioner with oil and refrigerant charging into the air conditioning system will be - 6 400 rub
Replacing two tubes of the rear air conditioner with filling oil and refrigerant into the air conditioning system costs - work 12 000 rub
The benefits are obvious!

At the same time, do not forget about the annual scheduled maintenance of the main air conditioner. After all, it is much cheaper and safer to prevent trouble than to spend money on expensive repairs. We include the following works in our annual service:
Flushing of two radiators for engine cooling and air conditioning with removal and flushing from both sides and refilling of refrigerant and oil (recommended refueling and oil change in the system every 2 years) from 6 600 rubles to 8 100 rubles.
Replacing the cooling fan of the air conditioner radiator: operation - from 700 rubles
Cabin filter replacement. Work - 408 rbl
Antibacterial treatment of the system - from 760 rbl before 3 333 rbl(more details).

* Prices are for reference only and are not an offer.

If you notice that an air conditioner is in your Mitsubishi Pajero 4 is not already producing enough cold, or has stopped working altogether. The masters of our tech. The center will carry out a full diagnostics of the air conditioning system and identify the cause of the malfunction.

The most common reason for a non-working air conditioner is -Freon estrus. The tightness test can be done in various ways. For this, an electronic leak detector is used, which reacts to the presence of refrigerant in the air.

However, it is not always possible to accurately locate the leak using a leak detector, then in the air conditioning system Mitsubishi Pajero 4 the diagnostic amount of gas is charged and added ultraviolet, which seeps into all microcracks and which can only be seen with the necessary equipment.
In order to start refueling, you must connect to both circuits of the car's cooling system and tighten the valves tightly.

Then the system starts up, it pumps out frion out of the system, weighs it and clears it.
The specialist who will fill the system accurately calculates the amount of refrigerant that needs to be filled for a particular car brand, since dosing refrigerant in the system- it is very important. A compressor overheated by unnecessary work, if it fails, will hit your pocket hard. For Mitsubishi Pajero 4 2015 the norm of the filled in freon is 870gr.
After full download freon the valves are disconnected; to check the system's performance, it is enough to start the car and turn on the air conditioner.

Warning

The air conditioning line is under high pressure. Until the refrigerant has been completely removed, do not disconnect any hoses or remove air conditioning units. The removal of the refrigerant must be carried out exclusively by the dealer's workshop or specialist workshop. Even after removing the refrigerant from the air conditioner line, disconnect the hoses only after wearing protective goggles.

Air conditioning system device

The following is a list of air conditioning system maintenance procedures to ensure that it can operate normally for an extended period of time.

PERFORMANCE ORDER

1. Check the condition of the A / C compressor drive belt. If you find signs of wear or damage, replace the belt (see. subsection 2.6.4).

2. Check the belt tension, adjust if necessary (see. subsection 2.6.4).

3. Check the condition of the air conditioner hoses, for cracks, swelling, hardening, and mechanical damage, swelling from oil ingress and delamination. Check for tight joints. Replace the hoses if there are any leaks or obvious signs of damage.

4. Inspect the condenser fins, remove leaves, insects and other foreign objects from the intercostal spaces. For this purpose, blow out the condenser with compressed air, or clean it with a special comb.

It is recommended to turn on the air conditioner at least once a month for at least ten minutes. This should be done especially in winter, when, due to prolonged downtime, the oil seals and seals harden and their subsequent destruction occurs.

Air conditioning leaks are best shown when the pressure and temperature rise to operating level. To check for a leak in the system, run the engine for five minutes with the air conditioner on. Stop the engine and inspect the hoses and joints of the air conditioner. Oily leaks indicate refrigerant leaks.

Due to the complexity of the air conditioning system, and also due to the fact that it is necessary to use special equipment to diagnose the system, any maintenance and inspection work must be carried out by specially trained personnel.

If the air conditioner does not work at all, then check the fuse panel (see. subsection 12.1) and the air conditioner relay, which are located in the mounting block inside the engine compartment.

Insufficient refrigerant charge is the most common cause of poor air conditioner performance. If there is a noticeable increase in air temperature from the air conditioner, then check the completeness of the refrigerant charge as described below.

Refrigerant charge check

PERFORMANCE ORDER

1. Warm up the engine to normal operating temperature.
2. Move the air temperature control lever to the position corresponding to the lowest temperature, set the fan speed to the highest. Open the doors (to prevent automatic shutdown of the air conditioner after cooling the passenger compartment).
	3. Check compressor activation. When the compressor is turned on, a click is heard from the electromagnetic clutch, and the central part of the clutch begins to rotate. After the system reaches operating temperature, feel the temperature of the two evaporator tubes on the bulkhead of the engine compartment. The evaporator outlet tube (larger diameter) should be slightly warmer than the inlet tube (smaller diameter).
	4. The tube from the condenser to the evaporator (smaller diameter tube) should be cold, and the tube from the evaporator to the compressor should be slightly colder (by about 2–6 ° C). If the outlet pipe of the evaporator is significantly warmer than the inlet pipe, the refrigerant charge is insufficient.
5. With the air conditioner running, bring a thermometer to the center of the air exhaust duct. The air temperature at the outlet from the duct should be 17–20 ° C lower than the ambient temperature (and not more than 20 ° C). If the ambient temperature is very high, for example 45 ° C, then the air temperature at the outlet of the air conditioner can reach 15 ° C, although as a rule the temperature of the chilled air is 17–20 ° C lower than the ambient temperature. If the temperature of the chilled air is higher than the common temperature, then it is necessary to add refrigerant to the air conditioner. Further work on the air conditioner is outside the scope of this manual and must be performed by trained personnel.
	6. Check the condition of the refrigerant through the sight glass. The sight glass is located at the top of the receiver (indicated by the arrow). If foaming is observed in the glass when the air conditioner is running, the amount of refrigerant is insufficient.
7. At high ambient temperatures, bubbles can be observed in the sight glass, even with normal refrigerant charge. When the air conditioner is turned off and the amount of refrigerant is normal, a slight foaming is observed in the sight glass, which subsequently disappears.
8. If the checks indicate that the refrigerant charge is insufficient, the vehicle should be returned to the dealer's auto service or specialist workshop to recharge the refrigerant.

Heater

If there is no air heating in the heater, then the reasons may be the following: either the thermostat does not close, as a result of which the liquid heats up insufficiently and does not warm up the heater radiator well (in this case, replace the thermostat (see. subsection 4.3)), or the heater hose is clogged, which prevents the flow of fluid through the radiator. In this case, flush the hose:

If the fan speed does not match the position of the switch, then the fuses, wiring, switch, resistor box or motor must be checked (see. subsection 3.3.14).

If air does not flow from the air duct outlets, then proceed as follows:

If the mat is damp or coolant vapors seep through the ventilation holes, there is a leak in the heater radiator. Replace the heatsink (see. subsection 4.5), since the heater radiator is usually not accepted for repair.

Check the heater / air conditioner drain hose, which is located on the right side of the bulkhead of the engine compartment, for blockage.

Autoconditioner repair on Mitsubishi Pajero 4

Mitsubishi Pajero 4 is equipped with a modern air conditioning system with several zones. Each of them is adjusted independently and forms the optimal microclimate for each passenger and driver. The back contour of the car air conditioner is the most painful place here.

Why can such a breakdown occur?

Corrosion is the main reason why the rear circuit of the air conditioner in Mitsubishi Pajero 4 breaks down. It leads to complete rotting. Also, this process is significantly accelerated by the reagents used to treat the roadway. The car owner also contributes. The more often Mitsubishi Pajero 4 moves off-road, the faster the rear air conditioner circuit breaks down. Consider this if you do not want to carry out repairs often.

What is important to know about renovation?

The rear circuit of the Mitsubishi Pajero 4 climate system is responsible for creating a favorable microclimate for passengers. Structurally, the lines of this circuit are laid along the bottom of the machine. In case of excessively intensive use, and especially in winter, the tubes of the air conditioner fail in just one season. Of course, the problem can be solved under warranty. However, many car owners put it on the back burner. As a result, there can be no question of any comfort.

The rear circuit of the Mitsubishi Pajero 4 air conditioner can be repaired even several years after the breakdown of this element. In such a situation, it is most reasonable to use special high-pressure freon hoses. The use of such a spare part is the most expedient from the point of view of costs. The hoses are distinguished by increased reliability indicators. For a long time, they do not lose their original properties.

Local repairs are allowed as a temporary measure. But it is only possible if the tube is rotten in only one place. Also, for a short time, you can simply turn off the rear circuit by installing plugs. Such a solution to the problem will cost a small amount.

Repair of the rear circuit of the air conditioner in Mitsubishi Pajero 4 can be entrusted to a master, or you can do everything yourself. Even for an inexperienced driver, this process will not cause any difficulties. No special skills are required here. You just need to familiarize yourself with the relevant information on thematic resources.

Where should you buy freon hoses and can you replace them yourself?

Do you want to buy autoconditioner hoses for Pajero 4 and be 100% sure of their quality? On our site Avtoxolodok. You can always order a ready-made set of air conditioning hoses for Pajero 4, for installation instead of aluminum pipes in the car air conditioning system.

On sale are the original products of the Avtokholodok company. The hoses will last a long time and will not cause trouble during the entire operational period. This is due to the fact that they are less susceptible to oxidation than pipes. Moreover, the price of such a spare part is low. Carry out repairs competently and do not know many problems!

Are you not satisfied with the temperature in the car? Are you annoyed by odors and an arbitrary shutdown of the cooling system at the most inopportune moment? Then you need a Mitsubishi Pajero air conditioner repair, which our masters are ready to carry out for you in the shortest possible time and with consistently high quality. Our repair is a guarantee of a comfortable microclimate in your car. When the help of specialists is needed Inspection of the car air conditioner is recommended to be carried out approximately once every 6 months. This will eliminate any errors and malfunctions in its operation, and also guarantee effective functioning until the next preventive maintenance. The following factors may indicate the need for an immediate appeal to specialists:

Weak level of interior cooling;
The system is running out of refrigerant;
The operation of the air conditioner is accompanied by extraneous noise;
When cooled, the interior fills with unpleasant odors;
The unit is switched off in an arbitrary order.

Major breakdowns

Most often, the repair of the rear circuit of the Mitsubishi Pajero air conditioner can be caused by the following provoking factors:
Sealing problems;
