my lumina has a 3.1 and was overheating, while looking for the reason i found a coolent leak at intake gasket under themostat housing. so far this is just a minor problem,i replaced temp senser ,themostat,switched relays ,checked fuses.. i have 2 fans one that comes on according to coolent temps ( is working good now since changing temp senser) now my problem is... that the second fan that is suppossed to come on when ac clutch is engaged is not coming on at all, i pulled out the relay and jumped across relay terminals and got fan to work but when relay is installed ,nothing ! would this be a problem with ac compresser or a related switch?
