Q: Q: AC blows no cold air

asked by on

The AC works, but it is not blowing cold air.

It sounds like you may need to have the AC system charged. As the car gets older, hoses and o-rings begin to leak refrigerant. You can add some UV dye in the air conditioning when you charge the system to help find the leaks. The most common places to find leaks are on a flex pressure hose, the Schrader valves and o’rings where the metal pipes connect, and out of the seal on the compressor. I would recommend having a technician from YourMechanic come out and run a thorough inspection of your AC system, which will likely include checking for leaks, and adding some refrigerant to the system.
