I've got the temperature controls set to auto, and at most fan speeds there is a wind whistle coming from the vents. The blower motor itself doesn't sound too bad (in the spring I will find it and give it a good dosing of lube in the bearings), but there is a definite wind whistle, although slight, coming from the vent system. Any suggestions on where to start looking to fix this?

Start with "ALL dash vents full open - especially the left and right outside vents..

its going to be the air channel right above the battery. there is a foam gasket there that usually deteriorates by now (it did on my 2013); OR it is not seated correctly.

Thanks, I found your post in one of the threads, I'll look at it closely this weekend. But, for me it is there sitting at a light or moving. So, could still be a part of the problem, but could also be cabin filter, or or … Some things to look at closely though.

I ended up replacing the cabin filter, that seemed to do the trick. previous filter looked fine, swapped out, whistle is gone.
