I need some help here. My ac will only come on for a minute then turns off, a few minutes later it comes on the same thing. Here is what I have done so far. Replaced dryer, pressure switches, and expansion valve, converted to r134 (removed ac compressor and drained the put in 5oz of Pag oil) and replace aux low speed resistor. I vacuum system down for 4 hours and check to see if it holds. Check good. If I supply power to the compressor directly it works fine and cools great. I have check all relay and fuses. Sometime it will stay on for five minutes and cools great. The Bently manual refers to a ac compressor clutch control relay which I cannot find. My car was built 8/90. Any Ideas???
