Question about 1998 Chevrolet Cavalier
My a/c suddenly stopped blowing cold air. I cannot hear the compressor come on so I can add freon to the system.
You need to check the compressor clutch first it should come on automatically low Freon wouldn't stop it from coming on but im not an exspert on this system. so with out looking and doing a couple of tests cant give you a definite answer. check the breaker first thing. [fuse]

this is caused by a defective temperature control blend door actuator motor. Don't overhcahrge the system, if one part of dual climate works ok the problem is not the compressor or the system charge

The compressor cutting and out is a good sign that the system is trying to work. Usually when the compressor cuts in and out after a few seconds, it means that the system is not fully charged and more refrigerant is needed. It's a good idea to purchase a gauge that measures the amount of charge in the system. The gauge looks like an air gauge, and they are not very expensive. That way you will know how much more of a charge the system needs. The gauge hooks up to the low pressure valve, just as the charge hose does.

If you are absolutely confident the AC compressor is not kicking out on low pressure then it is the blend door actuator.
The blend door determines how much air blows through the heater core or evaporator.
The actuator can be purchased at dealer and maybe at a local part store.

If the freon is full and the compressor clutch is working,is the blower working, need more details, if it is, you could have a blocked orifice filter. or a bad high pressure switch located at the rear of the compressor.if the high pressure switch loses voltage or goes out, your cool air will come to a dead halt. check the high pressure switch for voltage. good luck!
