The Tahoe has had an annoying grinding noise coming from the headliner since I got it. Pretty subtle but with the stereo off quite annoying.
Turns out it has a temp sensor with a fan in it and they go bad. GM calls it an “aspirator” I just call it “that seems overly complex”
Anyway, now I have the part. It was about $50. Just have to put it in at some point…
