I have 1994 LS, and my problem is that the compressor works fine, but every so often it engages and dis-engages a number of times, with the fan not active. Then it will engage again, and the fan wil activate and everythings works fine again. When I set the LCD control to LO setting the compressor appears to work fine. When it is set at anything above LO it will operate just fine and then it will go through this cycle again. I have changed the receiver dryer, the pressure switch, the resistor in the rad shroud, and the temp sending unit from the rad works at the posted setting. My question is could this be due to a fualty contact in the LCD control module?
