    Air Conditioning blowing hot air

    I had a coolant recharge around this time last year on my 98 Camaro and after not running for a while I started it up and the A/C only blows warm air. I'm not sure if I need another recharge or if there's a leak or if the compressor is going out. Has anyone experienced this problem as well?

    There are a number of possible things that could be causing your problem. Some are electrical, some are mechanical, and some deal with the refrigerant charge. Check all of your related fuses, look around for oil leaks around the condenser, compressor and hoses, and if you don't find something obvious there save your time and money by having the system checked by a shop that you trust. Without the right equipment to determine if you have an electrical problem, bad compressor, system leak or imbalance you would just be making guesses and in the end usually either not getting it fixed or spending more money than necessary to get it fixed.

    Assuming the AC compressor clutch is not engaging with the AC turned on, a quick and dirty test for a low refrigerant charge is to jumper the pressure switch to see if the compressor will engage.
