Blowing Radiator (Cooling) Fan Fuses

[Bouche Dag]

Car is a 92 AWD.

I noticed my car getting quite hot last night on the way home. Limped it home and checked everything out. I thought the switch had gone bad but that wasn't the case. Replaced it and then found that the fuse on the + terminal for the rad fan was blown.

Replaced it and it blew again after a drive down the block.

It should be noted that I found the overflow tube wrapped around the fan as I was investigating the issue.

The fan still spins somewhat freely (I'd say about 3/4ths of a full revolution when I spin it by hand). And there are no awkward or unusual noises when I directly power the fan with a 12v power source.

Correct me if I'm wrong but the fan should spin a lot more than 3/4-1 revolution when spun by hand? My thoughts: the tube getting caught caused excessive strain on the fan motor, drawing excess amps blowing the fuse. Now that the fan only spins 3/4ths of a revolution it's drawing excessive amps, blowing the fuse.


RESOLVED: The fan motor was bad. See last post.

Your theory sounds like a good one to me. Your fan motor is done for. A new fan will most likely fix your problem. Good luck.

I ordered a godspeed slim fan (a mod that I wanted to do anyway since my aftermarket j pipe already has clearance issues and since the stock fan is quite the eyesore). I will report back with my findings after install.

Could someone do me a favor and run out to their car and spin their OEM fan by hand and let me know how many revolutions they get? I am just curious to know if my fan is in fact revolving less than it should...

your fan is definitely seized up. same thing happened to mine. replaced it and all was good.

Awesome. I love your confidence. I thought the same since this problem just recently started after the overflow tube got caught.

Update:

Installed a new radiator and slim fan (pusher) and voila, no more issues. Plus the engine bay is a lot cleaner without that ugly huge stock fan.

Thanks for the help as always guys!
