These damn fans, tried everything!
alright, the cars a 93 formula. i have a 160 stat with a pcmforless chip with programming to turn the fans on early. the other week they just cut out and neither will come on at the lower temp or the stock temp. ive replaced the coolant temp sensor in the water pump (that one goes to the pcm, the one in the head goes to the gauge), ive replaced the relays, i have voltage at the relay ports. WTF? i have to turn them on with my home made switch. what am i missing? everything should be working. is it possible that a power spike or something ruined the fan programming on the chip? is that even possible? i need this solved without paying big bucks before the summer heat gets here. any suggestions would be great, thanks!
