Does resistance when spinning a fan by hand indicate anything? The 8 fin fan on the passenger side spins great. Driver's side doesn't spin nearly as well. No debris lodged on either one. I'm guessing the motor is burned out? I can at least get one to run when I put the A/C on.

Going to my dad's shop tomorrow and he'll be able to jump the fuses. Just thought the resistance when spinning was significant.

Set a multimeter to ohms and check the fuses. There are 3 cooling fan fuses and a 40amp fan fuse. Hopefully all you have is a bad fuse. Autozone or napa should have them. If not, stealership. Good luck bud.

The AC is a test i should have suggested sooner.... Turn it on, they should come on.... I just do not remember the speed. I think it is high...

40 amp fan fuse was blown

Now you need to determine why it blew. Something is drawing too many amps. Fan Motor/s?

Yeah I dont wnt to buy a fuse just to have it pop again.

Should I be good to go once I buy the fuse and cooling fan motor?

I suggest testing to see which ones is bad. Jumpering relay 1 seems to place the fans in series. If one is not turning, that is the bad one. If the fuse blows, it could be both.

Dang, well I hope its jsut one.

Sometimes fuses blow because they are old. Definitely replace and see if it blows again. You might not need a motor, fix the cheap thing first.

Went to Autozone and bought 2. Put the first one in and fans kicked on at 188F. Went up to 190 and then went back down. Took the fuse out and tested it. It didn't pop. Yippie!

Right on :-)

Gonna be a hot weekend!

So after 2 days of driving fine, the fuse popped again. I was just wondering if the tuned fan settings adversley effect anything? Or is the shorted fan motor/motors entirely to blame?

The fan settings have nothing to do with it, you need to replace your fan(s). But first properly test things.

It indicates the fan motor is pulling too much power. There can be a lot of reasons for that, including it just might be dirty. I still wouldn't be looking at a complete replacement yet, but it sounds like you're at the end of your testing ability? The fact that you can feel resistance and otherwise it works ok almost definitely means there's something stuck in it, preventing it moving freely. This can cause a perfectly good motor to pull extra current. So I would be looking for bad bearings, grass our other fibers around the spindle, that kind of thing. Depends on how much work you want to do though, as a whole new fan assembly will almost definitely fix it.
