all my grounds are nice and tight and clean. i have the switch so i can turn my fans on so i dont over heat. the fans never engaged with my ac on cuz, well, my ac compressor is bad and i cant turn my ac on, thats something ill get to eventually! there is the constant 12 volts at the relay and i just connect them with my switch to turn the fans on. when the car is on, there is another 14 volts present, that is not present when the car is off. all my fuses are good as they were the first things i checked. im sure one of those diagrams applies, im gonna print them out and see if they help. i just wish i had a way to test to see if the ecm is actually sending the signal to engage the relays and start the fans. im sure there is a way but i do not know it and those crap haynes manuals are no good. does anyone have a shop manual for a 93 formula firebird? the ecm is the unknown in this equation as ive replaced or checked the other factors. piss, piss, pissin me off....
