Which FSR to buy?...
 

I'm getting a quiet squealing from my fan when I press MAX. I'm aware that it's probably my fan motor dying a slow and painful death, but I'd rather at least try the cheap and quick FSR fix. A quick search of eBay yields the following:

Does anyone have recommendations/warning about which FSRs to buy? Should I spend $90 on an OEM BMW one, or just any cheapo on eBay?

Thanks in advance,

The FSR ONLY affects fan output speed, it is what tells the fan how fast to spin. It will not cause any noises.

I got an E-bay FSR (non-OEM), it only lasted 6 mos. Had to replace with the Valero (OEM). Been good so far. Go OEM.

I may have run into this too (if so, my eBay one only lasted a year and a half). Maybe my 7 3/4 year old battery wasn't dead yet! I'll find out next week when I replace the FSR.

An update: Changed the FSR today and it appears to have fixed the problem. So the inexpensive ones on eBay may be poor quality (or maybe it's a problem with the HVAC system that burns them out).
