Over Heating

I have a 1993 Civic EX Automatic with 195,000.

The problem is that the Temp rises when the car is in idle and the A/C is on, the condenser fan and radiator fan are good, the relays for the fans and the compressor relay are also good. As long as I am at highway speeds it is fine due to the air flow. The Compressor Clutch seems to stay engaged as I cannot hear it cycle in and out, it only heats up when the clutch does not cycle. I do not know if the Clutch is bad, or the pressure switch, or something else, I prefer to buy the parts myself online and either take it locally or do it myself. I have not checked the R12 pressure.

I assume that it is the temp of the engine that rises. I believe that you have a leak in the cooling system. Not A/C. You might have the cooling system pressure checked.
