hmm i think that harness has 2 main grounds, one down by the starter, and one somewhere on the drivers side of the trans or top of the motor.



havent looked in a stock fc bay in a loooooong time lol.

Ahhh damn. Would you happen to know a site that has diagrams and such for the FC?

A guy checked out my FC and said there might be a short in the wires and what not. Could it be possible that the power mirror, AC and clock wires be close together? Another thing that I should have mentioned is that when the things WERE working, when I had the AC on, little water beads start forming under where the compressor(?) is, could it be possible that the water shorted out the wires? I appreciate the help!

Condensation droplets, which would certainly be expected to form on the cold metal surfaces of the low-pressure side of the system, shouldn't cause any problems.



If the compressor is coming on when you turn on the A/C and the unit is blowing warm air, then I would strongly suspect a low charge. Or, as Kevin has suggested, it may be due to a clog in the system if it wasn't evacuated properly before being recharged. The receiver/dryer must always be replaced whenever the system is opened. There's also an orifice tube or some such thing that I believe is a different size, depending on what refrigerant you're using.



I understand your interest in solving the electrical problems, but if the compressor is coming on, and the fan is blowing air through the dash vents, then there is no other electrical part of the A/C system that could be causing it to blow warm air.



Only other thing I can think of is that you could somehow have the heater on.

Hmm... when you turn the AC on, is the light suppose to come on? When I bought the car, the AC was working fine even though that light didn't go on.
