Review on 💨 ACDelco GM Original Equipment 15-73513 Air Inlet Door Actuator: Efficient Heating and Air Conditioning Solution by Marty Drury

Installed on my 2006 Pontiac G6. This part controls the ventilation flap, which switches between outside air and recirculated air. The original part had a broken gear which caused the mechanism behind the glove box to slip and rattle. Installing this part solved the problem and the noise. It took me about an hour to get the job done, although it could have been done much quicker as I was unnecessarily careful when removing the glove box and passenger side access panels (I didn't want to break anything, but all the plastic parts are surprisingly strong and some of the retaining clips definitely require some effort to remove properly).
