My apologies, I am powerless without the search function and apparently no matter what I type, "Sorry - no matches. Please try some different terms." Not sure why...

Anyway, my fans are blowing the 60A fuse. A terrifying experience when you notice temps starting to rise and see unending traffic with no where to turn off. I'm told the most common issue that causes this is the drivers side fan, which after years of being directly under the battery and such, garners more moisture than the passenger side fan, tell tale sign of slight rust colorization around the motor. So chances are this fan is my problem.

If I disconnect this fan at the cooling fan connector, will this allow just the passenger side fan to operate? Looking for at least one of the fans working for the time being until I can replace it, unless that fan isn't the problem. I assume if it still blows the fuse (if this method even works) then it will be the passenger side fan or a relay grounding out. Is this a safe assumption? Since both fans are... 15A each(?) I assume it would take a motor being fried to cause a 60A fuse to pop instantly.

Hopefully later my search function will be working again, but in case, OEM fans or is there a better "go to" option?

Input much appreciated! Thanks.

Honestly, if you can avoid it stop driving the car until you can fix the problem. An easy test would be to run battery voltage to your fans and see if they turn on. If your driver side fan does not turn on with battery voltage, its safe to say its done for. If it does turn on, look towards your relays. If your relays are good then you may have a chafed harness that has grounded out.

Here is a thread that I posted showing the wiring diagrams and a description of the operation of the fan system

You should be able to unplug one of your fans and have the other still work. Certainly not advisable and it probably would be best for you to park the car till you figure out the issue but that could be a problem if it is your only means of transportation.

I would also definately check the wires going to the fans as they may be shorted out as Mrmatt3465 suggested.

Single fan wont keep temps in check in traffic for long....esp TX. Sounds like fan motor dying pulling way too much amp....as stated..wire fan and check amo draw..inspect wires...good luck

"motor dying pulling way too much amp"

Deleted my post... didn't see was covered already.

I went through a shitload of problems with the stock fans blowing the 60 amp fuse too.

one of them decided to heat up and melt the entire shroud away causing the fan to fall into the radiator itself. then I also had troubles with my wire extensions on the fans (had to extend for blitz fmic) melting the electrical tape and causing the fans to short themselves out.

after much messing around with them and getting another lower mileage set, i haven't had a single problem with them since. goodluck !

I am about to post 2 sets in the FS section:

Both are low mileage (under 30,000 miles) left over from frontclips I parted out

I have a:

Series 6 set $165.00 Shipped

Series 7 set $257.50 Shipped (Newer and a little bit cleaner)

Both are on the shrounds still, bolt up, plug in .. and go!

Check the FS section in 1 hour...

Finally got time to dig into the car.







Yay. Sparks.

So, is this repairable or in need of replacing? The fiberglass IC duct sits firmly on the wires apparently, which caused what you see to the passenger side fan.

FSM says I need to drop the radiator to remove these fans, is there a way to remove this without dropping the radiator? Can the fan motor, once removed and repaired/replaced, be rotated within the mounting bracket to move those wires from the pinch point?

Fan still turned on and spun to speed; I had disconnected the driver's side fan and replaced the fuse assuming the drivers side fan was the culprit. I noticed sparks fly once the passenger side fan turn on, yikes.

Get a good used set of fans, they won't cost you much. The fans are important enough that it's not worth dorking around with broken ones.

I think you can pull the fans with the radiator in the car, but really the hardest part is pulling the IC, battery, etc. to get down to them. Once you get down that far you're almost there for pulling the radiator.

If you have a stock radiator, now is a good time to get an aluminum one.

+1...the time it would take to replace/repair fan motor and wires, better off just getting new set of fans. You should be able to remove without dropping the radiator as Dale said.
