I'm stumped. I just put a new engine in my car and now can't get the fans to turn off. Both fans kick on to high speed as soon as you turn the ignition to on.
I've the checked the connectors on the t-stat housing many times, replaced the fan switch in the radiator, checked the connections where the relay or resistor or whatever it is was spliced out, checked and swapped relays, checked and replaced fuses, and can't figure out what is going on.
The gauge in the cluster works, the logger reads between 96-98 C when fully warmed up, and the thermostat opens.
What baffles me is the fans worked fine before I pulled the engine. They even worked fine the first time I started the new engine. The first time it got up to temp both fans kicked on and now they are always on with the ignition.
What would cause both fans to kick on to full speed like this? I'm aware of the spade connector on the rear of the t-stat housing being a sort of "back-up." Is it a back-up if the fan switch isn't functioning? Could it be bad wires somewhere? I need help. /ubbthreads/images/graemlins/banghead.gif
