What are the reasons for the Roewe RX5 air conditioner not cooling?

[RhettMarie]

Lack of refrigerant, dirty air filter and condenser, circuit problems. The following are the reasons why the Roewe RX5 air conditioner is not cooling: 1. Lack of refrigerant: The refrigerant in the air conditioning system pipeline is insufficient, the pressure decreases, and the heat taken away becomes smaller. There will be slight leaks in the air conditioning pipeline or condenser, which is a normal phenomenon. If the refrigerant is insufficient or too little, it needs to be replenished. 2. Dirty air filter and condenser: Long-term lack of maintenance, dirty air filter and condenser, or clogging will result in poor cooling effect. If you do not have the habit of regular maintenance of the air conditioning system, you should perform a thorough cleaning of the air conditioning system and replace the air filter. 3. Circuit problems: By directly supplying power to the compressor electromagnetic clutch, you can preliminarily check whether the compressor has a problem. Generally speaking, the compressor rarely fails directly. If it is a problem with the compressor, it is recommended to leave it to professionals to handle.

Having worked in auto repair for so many years, I can tell you that common causes for the Roewe RX5's air conditioning not cooling include refrigerant leaks (system freon leakage), compressor damage, or belt breakage, all of which affect the refrigeration cycle. A clogged condenser impacts heat dissipation efficiency and often causes issues on hot days. On the electrical side, blown fuses, relay failures, or control module malfunctions can cause the system to stop working. A dirty cabin air filter can also reduce cooling capacity. It's advisable to first check and simply replace the fuse if needed. If that doesn't work, you'll need to visit a professional shop to use diagnostic tools to locate the leak. Driving without air conditioning in hot weather is dangerous and can lead to fatigue, so don't delay repairs. The RX5's compressor can sometimes be less durable, so regular maintenance can help prevent issues.

I've been driving the Roewe RX5 for several years and encountered an issue with the air conditioning not cooling. It turned out the refrigerant had completely leaked out, and a simple recharge of Freon fixed the problem. Other possible causes include a faulty compressor, debris blocking the condenser surface, or a heavily dust-clogged air filter, all of which can affect cold air output. You can first remove the filter yourself to check for dirt—replacing it is very inexpensive. If you notice a strange odor under the chassis, there might be a system leak. Driving in high temperatures without cool air is very uncomfortable, so it's best to get it checked quickly to prevent compressor burnout. Parking in shaded areas daily can extend its lifespan. Overall, the RX5's air conditioning system is quite reliable.

I bought an RX5 less than half a year ago, and the air conditioning stopped cooling. After inspection, it was found to be caused by low refrigerant pressure, which was resolved after replenishment. Other potential fault points include temperature sensor errors, poor electrical line contact, or expansion valve blockages, all of which can lead to similar issues. Don't worry, try restarting the air conditioning system—sometimes the module needs a reset. Keeping the filter clean is crucial as it filters the air and prevents blockages. Address the issue promptly to avoid major repairs.

I have a good understanding of automotive air conditioning systems. When the Roewe RX5's air conditioning is not cooling, possible causes include insufficient refrigerant (requiring replenishment or leak repair), burnt-out compressor coils, or dirt accumulation on the condenser fins affecting heat dissipation. Poor contact in control relays or switches may also interrupt power supply. A simple test: start the air conditioning and listen for any noise from the compressor; if there's no sound, it might be an electrical fault. Regularly cleaning the condenser can improve efficiency. The system is prone to failure in high-temperature environments, so it's recommended to keep the fan speed at medium when using the air conditioning. The RX5's circuit design is reasonable, but aging components need timely replacement.

I suspect that the lack of cooling in the Roewe RX5's air conditioning system may be caused by a system leak or compressor failure, which interrupts the refrigeration cycle. Loose or broken belts can cause the compressor to stop rotating, affecting normal operation. Poor heat dissipation from the condenser is more noticeable during traffic jams, reducing cooling efficiency. Electrical issues, such as blown fuses, are common causes. When encountering such problems, immediately open the windows for ventilation to avoid discomfort or accidents caused by excessive heat inside the car. Promptly visit a repair shop for pressure testing and refrigerant recharge, as the overall cost is not high. The RX5 model is easy to maintain, and regular inspections can reduce sudden failures.
