Hi all, I've got a 2013 Murano. The AC blower went out so I purchased a replacement. Easy single plug and play. After installation I notice a high pitched ringing sound when I use the AC. (Similar sound to the ringing in your ear after a concert) it's just loud enough to be annoying and it is constant. I tried turning the radio off thinking it may be interference noise coming through the speakers, but does not change. It stops when I turn off the AC fan.
I returned and replaced the fan thinking it may have been faulty, but this one does it too.
Any troubleshooting thoughts welcome. Thanks

My best idea is to pull the new motor/fan combo and look inside to see if there is any debris touching the fan when it rotates. Maybe others can do better.

And BTW - change the cabin filter if you haven't done so recently.
