fiero question, can't find the part I need!

carcrazy02February 15, 2008

Hi! I have an 84 Pontiac Fiero. The other day I came home and turned the engine off and the radiator fan in the front stayed on. I disconnected the battery and have been searching for the part ever since. I think I need a relay, however, I can't find the part that is in my car at any auto parts store. I even went to the GM online and the part wasn't on their site! I looked for "radiator cooling fan relay", but maybe this one is called something else. When I unplug this part that is in the picture, the fan turns off, when I plug it in, the fan turns on... if the engine is running or not! Maybe it's called something else? Maybe it's just so old that I have to find it at a junk yard. I've checked Napa, Pep Boys, Advance, Autozone, and Central Auto Parts. None of them seem to have it!

This is a picture of what the one in my car looks like...

Any help or advice would be greatly appreciated!

Best bet is to go to a dealer and find the oldest partsman possible. He might remember it.

I bot a 84 Bonneville new. In 1994 I needed some small carburetor part that controlled the fast idle. I had the correct name as I had the shop manual. Well they changed the name over the years. Parts man took a flying lucky guess and came up with the right thing but had never "heard it called that before."

That piece in your hand, was every wire going to it black?

It looks like a grounding bar, or otherwise referred as a ground bus. Instead of making multiple splices, they use a "comb" inside of the bus and then connect as many grounds as they need to. I suspect the reason the fan turns off is because you are removing the ground to the control relay, or the fan ground itself.

Further diagnostics are required.......

What does that harness connect to????

I have that same part just lying under my driver's side headlight. (disconnected)

I have searched everywhere for the end to plug it into, but to no avail. Also, my fan hasn't worked since I bought the car a few months ago.

Fieros... a partsman's nightmare. Good luck. Your best bet may be to find a fiero club in your area.
