The fan must run,or the motor will overheat. My 95 sc1 was overheating. The fan was not comming on. So I ran test wires to the battery and the fan came on.Must be a bad relay somewhere.So I ran wires from the fan to a switch I installed on the dash.Anytime the temperature gets near halfway,I turn on the fan and it drops to a quartar. Hope this helps.
with the compressor running.

the compressor is places a drag on the engine,as a result it would generate more heat but the car should not be overheating. The fan motors should be on when the a/c is running.
If the fan outside is not running the compressor will overheat and if the fan inside the house is not running the compressor will get liquid refrigerant back to it and lock up! Neither is good for the compressor.
overheating, or running too cold
Typical causes of a compressor not running are: low coolant, blown fuse in compressor circuit, bad compressor, bad temperature sensor.
If the compressor has stopped running altogether the AC will not work.
yes but if the compressor does not work there is no reason for it.
Is compressor running? If refrigerant charge is low it will not
If the compressor is running, either the compressor has an internal fault or the refrigerant has been lost. If the compressor is not running the thermostat or the compressor may have failed. If the compressor is getting hot and switching off at regular intervals, the refrigerant has been lost. In any case a refrigeration engineer visit will be needed to prove the fault.
If the clutch disengages properly then the compressor should not be running. Most likely the clutch itself is bad instead of the compressor.
