I was checking my 97 K3500 7.4 for transporting my kids to college. I noticed the auxilary fan did not come on with the AC compressor. I thought in the past it has.
???is is supposed to or only come on with high coolent temperature???

I was trying to debug it. The fan runs with 12v applied to it. There is no 12v at the connector benind the grill. The GM repair manual makes a reference to a control relay on the left side of the engine compartment not in the fuse relay center. There is a relay hanging off the engine side of the fuse relay center does any body know where the relay is.

Also while I had the grill off and knowing how it continues to crack, I ordered a replica grill(black, not chrome as original) and the turn signal lenses from Continental auto body parts. They will be delivered tomorrow.
