My radiator fan wont spin! The headlights and blinkers in the front work. However the parking lights will not light up, which is wierd since the blinkers work, hmm. The fuse under the dash is good and the motor is also good. I dont really know what else to mess with, I debated just running a wire strait from the fuse box under the dash and put a manual switch to turn the fan on and off with but Im not sure I want to do that. Any ideas on what the problem could be?

First I'd check the fan relay, which, I believe is located on the left side radiator support, mine is, on my 84. There is also a sensor like switch located on the engine block, different location depending on engine type, that would be my second guess. If I remember correctly neighter part is expensive, My 1984 fiero had this problem and it was the relay.

reasons why it dont work: bad fan, bad temp switch, bad relay, or corroded wiring/connector
couple things to try -
run power (12v dc) to the fan, see if the fan actually works
get the car up to temp where the fan comes on, about 1/2 on the guage (or if you have A/C, just turn on the A/C), and then check if theres 12 volts at the connector

I already tested the motor which is fine, Im not getting power to the connector. So would that be the relay? Im guessing the relay is that little box right near the drivers side headlight.

the relay, the temp switch, or corroded wiring.
my didnt work for the longest time, and it turned out to be the connector at the fan was crusty.
not sure where the relay is. the temp switch is on the intake manifold.

In my previous Fiero I did just what you said.
Ran wiring from the fuse block to the fan, with a rocker switch installed on the right side of the gauge cluster (in one of those black plastic covers). It seemed to work well, and I would turn the fan on when stuck in traffic in the hot Saint Louis summers (and when going through the emmission nazi testing).

Hey EMFORCE did you ever have a problem with anything having the fan plugged directly into the fuse box?

Replaced connector with a known good one I had lying around and still no go, I think im just gonna wire directly to the fuse box.

Anyone know how much a relay would cost??

There's a wireing connector right beside the gas pedal. The wire you want to splice into is green with a white stripe. Wire it to a toggle switch and ground the opposite side. It will operate the fan only while the key is in the on/accy position.

I just double checked how I had this done on my car for someone else
