I posted this on my.is but no one's exactly sure...

For the past several months, I've noticed a clicking noise coming from behind the dash regardless of whether my vent controls are on external or internal air. It sounds like some mechanism is trying to regulate the airflow temp and is having problems (sounds motorized, like the sound it makes when you switch between external to recirculated air). Someone on my.is suggested it's the blend door motor (which works in regulating the mix of warm/cold air according to temperature needs). It happens as soon as I start up the card, whether or not AC is on, and continues to happen the remainder of the time.

I took my car in for the 60k and the dealer couldn't figure it out (I claim ineptitude on the dealer's part as they couldn't understand what the problem was although it was clearly written in the workorder and is very audible when sitting inside with the doors closed) and they want to charge $200 just to look into the problem.

Anyone else have this issue and resolved it? My only workaround at the moment is to crank up the music. Any help is appreciated. Thx.

Bumpity...

 

I think i got the same problem with my GS.

I posted up a video clip of the noise....check it out and tell me if its similar to the noise you hear.

Hey, thanks for the post. Mine is similar and I think it is the blend door motor, as others suggested in your other thread. Mine's not quite a vibrating hum as yours, but more the sound of a mechanical hamster running on a wheel if you could imagine that

I'll try to post a small video later tonight when I get home. Unfortunately my car is out of warranty (60k) when this problem reared its ugly head and I'm not looking forward to a $400 repair

Thanks.

 

damn i have the same thing with my car. Ithought it was cuz of the charger or the wiring for the gauges but i guess not since you have it as well. If you ever find out what it is please let me know.

 

Didn't get a chance to capture the noise on video...went out last night to take it and it's the one time it decides NOT to make the noise

Another one of those ambient temp dependent issues I guess. We'll see.
