Hello all. I have a quick question about diagnosis an AC problem. Currently, the AC in my 1993 protege doesn't work. It worked fine until a small accident (I know this is going to be a pain to track this down). Now when I hit the AC switch, I hear the idle kick up and the radiator fan kicks on. The light does not come on neither does the condenser fan. I know the condenser fan works because I put power to it and it spun. The high side pressure showed something over 100 when I checked it last(i think it was like 130 but I don't remember, this was with the system off).

Is there any way to by-pass the system and force the compressor on? I assume I must have blow a sensor/relay/switch but have no idea what or where. I checked the fuses and relays in the box and they appear good, but I don't know where anything else is located. I've checked my repair manual but have not gleaned anything too useful. Is there anything else common I can check or how to proceed in trying to track the issue down. Thanks for the input.

 

Was the compressor touched or hit during the accident?
I would look at the AC clutch assembly.

 

It seems like compressor has damaged during the accident. Why don't you get it checked once.
