Q: AC not coming on at all

asked by on

AC was working and now it's not coming on at all
My car's transmission is unknown to me.

When you command the AC on do you hear the compressor turn on and feel the change in engine load? If the compressor does not turn on, may times this is because of a low charge from a leak. If there is power at the compressor clutch and no operation, the compressor will need to be replaced. Consider hiring one of our mobile experts to personally diagnose the issue with your AC firsthand and make the necessary repairs.
