I replaced the first fan in August. That replacement went out 3 days ago. It was under warranty so i got that one replaced free. The 3rd one stopped working today. Is it just bad luck or could the resistor be causing the issue? I thought if the resistor was bad, the fan wouldn't work at all, but it ran fine for 2 days and just stopped today after running for about 5 minutes. I hooked a battery up to the fan and it does not spin so i know it's dead, but could the wiring harness from the resistor to the fan cause it to blow? Any idea? Thanks in advance.

I suspected it was an off brand. Not saying for sure but I bet if you'd put in the AC Delco you wouldn't be having this problem. My original lasted 130,000 miles and when it started squealing I put in another AC Delco and it's been in for 30,000 miles so far. I try to use OE parts when I can.

When you say it stopped working, did it die in all fan speeds or just a couple. The problem is almost always the resistor coils, usually much cheaper than a fan and easier to change as well.

It would not spin at all. Funny thing is i went out today and took it off. Tested all wires with voltmeter and tested fan with an external power source and everything worked. Plugged everything back in and fan is working like new. Hoping it was a loose connection, but pretty sure I had tested that too. Who knows.

similar problem here...I changed out the resister and it worked fine for 2 weeks.
Yesterday the fan just quit entirely. Maybe the fan actually died now too...
