Common Volvo XC90 A/C Problems
There are a number of Volvo XC90 A/C problems which have been reported by drivers. The three most common involve refrigerant leakage, problems with the evaporator, compressor or faulty climate control. Below is an overview of each of these problems, why they occur, and what can be done about them.
This is a common air conditioning problem, and can be very frustrating to deal with. These leaks are caused by either vibration, or connections and joints within the unit that have weakened due to wear. Many air conditioning systems use copper, a metal which is vulnerable to corrosion resulting from environmental pollutants. Its tube walls are attacked and will eventually begin leaking in multiple areas if not addressed. In this scenario it is best to replace the coil. Other solutions for refrigerant leakage include recharging it, but this should only be seen as a temporary fix. Repairs are more expensive in the short term, but will protect the larger A/C unit and prevent it from long term damage.
Faulty Climate Control
The climate control within the Volvo is responsible for automatically regulating and controlling both the temperature and moisture within the cabin. If you detect that some vents aren’t blowing out air, this means that your climate control module could be having an issue. Given the fact that the climate control module is essentially a computer, any problems that occur with it will adversely affect the entire A/C unit. Due to the complexity of these systems, it is best to have it reviewed by a licensed technician.
The computers used by modern A/C systems are dedicated, and like regular computers they utilize software that requires updates. If the software is not kept update to date, or is subject to bugs or other problems, this could cause problems with A/C system performance.
The compressor is without a doubt the air conditioner’s most essential component. This is because it is tasked with the distribution and pressurizing of refrigerant. Therefore, if any issues arise with this component, drivers will quickly notice, because their air conditioner won’t produce any cold air. In fact, if the compressor becomes stuck, the engine might even seize.
A malfunctioning compressor might also make unusual noises. It is an intricate part that consists of multiple internal devices which carry out tasks that are specific. Should a compressor become damaged, oftentimes one of its internal parts will also be compromised, and as a result the component will begin making a grinding or squealing sound.
Finally, Volvo compressors use a clutch which is responsible for regulating when a compressor should be activated or deactivated. In the event this clutch becomes damaged, the A/C will either stay on permanently or will not come on. While the compressor clutch by itself can be replaced, many mechanics will recommend replacing the entire system so that you can save both time and money.
