Common Vehicle AC System Issues and How to Fix Them


Everyone loves the relief that air conditioning brings when driving in the scorching heat, but dealing with malfunctioning air conditioning in your car can be frustrating and uncomfortable. Air conditioning problems can also lead to serious issues with the engine if not properly maintained or repaired. Learn about some of the most common AC system issues and how to fix them.

Refrigerant leaks

One of the most common causes of AC system failure is refrigerant leaks. Refrigerant is what cools the air circulating through the AC system, and when it leaks out, the AC can stop working. Refrigerant leaks can occur due to old age or damage to the AC system. Your AC system will need to be checked for leaks, and you'll need to have the refrigerant refilled. A professional mechanic can assess the severity of the leak and repair it if necessary.

Malfunctioning AC compressor

A car's AC compressor turns refrigerant into a cool, refreshing breeze. When the compressor is not functioning properly, the AC system can?t cool down the air. Signs of a faulty compressor include loud noises when the AC is turned on or an AC system that's not blowing cold air. A professional technician should diagnose the issue and decide whether the compressor needs to be repaired or replaced.

Electrical issues

Even with a good refrigerant level and functioning compressor, electrical issues can still cause AC system failures. Faulty wiring, blown fuses, or other electrical malfunctions can stop the AC system from working. If you suspect an electrical issue, it's best to take your car to a qualified mechanic to inspect and repair the problem.

Clogged condenser

A car's condenser is responsible for removing heat from the refrigerant. If it becomes clogged, it can impede the cooling process and cause the AC to stop working effectively. A clogged condenser can be caused by debris that accumulates on the outside of the condenser. It's important to have your car's AC system checked regularly to ensure proper function and avoid costly AC repairs.

Bad AC fan

The AC fan is responsible for blowing air through the vents. When it malfunctions, the air conditioning system can?t circulate cool air throughout the cabin. The bad AC fan can be caused by issues with the motor, wiring, or wear and tear. A professional technician can determine the cause and make necessary repairs or replacements.

Dealing with AC system issues can be a hassle, but it's important to be proactive and address them promptly. Regularly maintaining your vehicle's AC system can help avoid costly repairs. Taking your car to a qualified mechanic to diagnose and repair problems is always the best option.

Keep Your Vehicle Safe

Hello. My name’s Samuel Jacobs. I retired from my job as an auto mechanic last year. During my years as a mechanic, I had the opportunity to meet people from all walks of life. Some have remained friends to this day. When I was working, there is one thing that I came across at least weekly. That is how uneducated people are when it comes to their vehicle’s tires. Properly cared for tires are crucial to the safety of your vehicle. Without them, your car isn’t going anywhere. If they give out on you while you are driving, there is the potential for serious injury. I’m going to share some tire safety information here. Things like the importance of correct inflation, how to check the tread, when to replace tires, tire rotation, and what to do in case of a blow-out. I hope you find this information to be helpful.
