Circuit Board? Posted by tibbidoh [Email] ![]() ![]() In Reply to: radiator cooling fan - 1985 Turbo, jw, Fri, 16 Jun 2006 17:48:15 Members do not see ads below this line. - Help Keep This Site Online - Signup |
JW,
I am not really sure what you are calling a circuit board, but in my 91,89,83,&79 900t's that I have owned the cooling fan circuitries have all worked from a thermostatic switch in the cooling hose that tripped a relay in the fuse box / relay center (has a plastic cover w/ 2 thumb screws holding it in place) the relays then just connected the juice to the fans via wires that enters from the bottom of the engine compartment and come up the center frame support of the fan. Now the newer the car the more complicated the relay wireing becomes, but that is basically it. The usual culprit is the thermostatic switch, either corroded connections or it has gone bad.
Try starting your car and turning on the AC at the very least the dirver's side fan should come on. For the cooling fan pull the two plugs off the little round thing on the upper radiator hose (close to the distributer, they usually have little orange rubber boots on the) and connect the wires toghther, the cooling fan should come on.
