having problem with aftermarket fans
having problem with aftermarket fans Fans not coming on, I have two aftermarket fans, both have a positive and negative wire terminal. they worked fine before the motor swap but now I can only get them to come on if I jump the relay's with a wire. I tried swapping relays and fuses already
maybe the relays you are swapping are no good, i had that problem when i burned my fuel pump relay and i tried switching it with another and that one turned out to be burned too, i was very confused for a while
Did the tune or computer get changed too? Maybe the setting is higher. Is the computer seeing the correct engine temps? ECT sensor ok? Did you switch from a 98 ecm to 99+? Do you have 12v on the opposite side of your signal wire of coil on the relay, either 85 or 86? One side should be ign+ and the other gnd signal(fan turn on) from ecu.
