My AC has stopped working on my car. The fan still runs, but no cold air. How do I know if it is the compressor or what?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Cathy, I suggest you have a repair shop, inspect your A/C system. A yellow dye can be injected into the system and after a few hundred miles, a black light is used to detect the source of the leak. You can hear the compressor clutch "kick on" if this is still operational.

Audra Fordin, Owner at Great Bear Auto Shop Hello Cathy, If there is no gas in the ac system, the compressor will not kick on. It is possible there is no problem with the compressor. If you are not getting cold air, you could have a leak in the AC system. When you have the car checked, they will put gas in (possibly dye too) to detect the leak.

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Cathy, There could be many reasons that you're not getting cold air. The most common is that the refrigerant is low. Now sometimes all you need to do is have a technician add it and you're good to go. It's also possible that you have a leak and this is why the refrigerant is low. Other possibilities are a bad compressor, blocked hoses or condenser or even a broken belt for the compressor. Your best bet is to take it to a shop and have it checked out. Unfortunately a/c problems can become costly. Many times more than one part has to be replaced and that's where the high repair prices come in. Lori Johnson
