I was in the process of chasing down a problem with my radiator fans where they would not come on high and actually blew the 60A fuse for the fans themselves when I turned the AC on. Well come to find out that underneath the plastic air duct (to my ASP medium SMIC) was rubbing the wires that go to the fan motors. The black and green wires were worn down to the copper and touching each other on one fan and the blue wire was worn down to the copper and touching the fan motor on the other fan.

I figured I'd post this to let everyone who might have this setup to be aware of this potential problem because I noticed my temps going up when the fans would not come on high. And they went up drastically when the fuse blew resulting in them not coming on at all. If it wasn't for me observing the water temp reading on my PFC commander it might have cost me the motor. Hope this helps anyone else from having this problem in the future. Thanks, Jerry

 

the batter tray can also do it. the battery is heavy and will burn out your motor. so make sure the battery tray is seated properly.

 

It's not so much the tray contacting the fan motor (you'd have some pretty serious radiator clearance problems if so); it's the battery leaking acid down onto the driver's side fan motor (a very common occurrence, due to the heat inside the engine bay) that eventually corrodes the motor wiring and fries it.

 

I would recommend if you have anything that might make contact with those radiator fan wires that you at least check it out every once in a while or use something to cover the wires (plastic tubing or even electrical tape) to stop it from wearing through. Cause if it does and you don't catch it pretty quick, fans won't work right and you might lose the motor from overheating.

 

1. Don't say thanks. Whoever read this is who should be saying thanks. I'll start it off.... Thanks for the lookout. I'm sure your precaution will help someone in the near future.

2. Good job noticing the problem. If you didn't you'd probably be posting a sob story about needing a rebuild... like what I wanted to do when I blew mine .

Thanks again
