Review on Enhance Comfort & Performance with GM Genuine Parts 22834330 Cabin Air Temperature Sensor Aspirator by Harry Love

Installed on a 2003 Hummer H2 - I didn't even realize the old one was loud until I started chasing the sound system hiss out of the speakers and accidentally noise discovered the grille attached to this thing. The Hummer manual says to remove the driver's side sun visor (not as easy as unscrewing it) and the A-pillar trim, then gently pull down from front to back. Since my sun visor wouldn't disengage from the bracket, I removed the A-pillar trim and slid the headliner along the top of the driver's door and along the driver's side sunroof trim to access it. and get to it without damaging the ceiling panel. The new sensor is pleasantly quiet.
