Chevy Cobalt Clicking Noise

I hope I got to you before you tried to fix the Chevy Cobalt clicking noise coming from behind the glove box. First, let's tell you exactly what the problem is. The clicking sound becomes an indication of a stripped gear inside of the air door actuator motor.

I found a gentleman on YouTube that made a video that shows you how to use wire ties to temporarily fix the [[Chevy Cobalt air door actuator problem]].

This means that the actuator motor never reaches the stripped gears. The question is how long will the repairs last. This depends on the age of your actuator and how much it gets used.

In other words this repair could last a couple of weeks or a couple of years. Nevertheless, this provides a quick solution for the Chevy Cobalt clicking noise that can drive you absolutely insane. You can install the wire ties as shown in the video and then order yourself a replacement
