Hey since this discussion has something to do with a problem im having and foff667 is a tuner extrordinare... my 93 LT1 bird will not turn either cooling fan on no matter what. ive replaced the coolant temp sensor in the water pump, replaced the relays, i have voltage at the relay block. i have to turn the fans on manually with my home made switch. i have a 160 stat and a pcmforless chip with programming for the stat. is there anyway that a power spike or anything could have "erased" the fan programming from my tune? they dont even come on at the factory setting. i dont know what else to check thats why im thinking maybe something went wrong with the chip, if its possible.
