I recently had enough from my climate control blower fan which was getting noisier by the minute. I had looked into servicing it earlier but these things are really made to just replace when they wear out so that was out the window. I priced a new one at the dealer (OEM part 87103-35022) and knew right away that option was out. So I did some research and finally bought a new TYC brand replacement fan. I have since installed it and the fan was a direct drop in. It certainly met all my expectations (no idea on longevity at this point, but I'll report back on any failures). Very quiet operation and it moves plenty of air just like the OEM version.
I bought it on ebay and would highly recommend this seller at least for this replacement part:

No affiliation with me whatsoever, just good service.
For those in Canada, he also ships USPS (which is a major plus!)
