GM Part #15844096.

This should work for all 06+ Monte Carlos with the Dual Zone A/C, but this was done on an '07 Impala SS. This should help all you guys with that have this problem and aren't under any kind of warranty or the warranty won't cover it like mine did.

ENJOY! (not my video)

 

Wow I hope that never happens to me. *Knock on wood*

Terrible vid too, but it's better than nothing. lol

 

lol I know, but I found it and it could help someone

 

This could of been helpful but I had i had it fixed under warranty, still paid the deductible.

 

that tick is nasty i'm gonna cross my fingers and hope this never happens

 

My 06 LTZ has it. It ticks for about one minute then stops, but only when the air recirculate is on, not the one that pulls outside air. It will tick the same amount of time again when the car is shut off. I just stopped using the recycle and forgot about it till now. My dealer is gonna hafta take care of that.

 

not yet on my car and I hope it never sounds like that!

 

mine does it and just have to change it to the recirculate button

 

Mine used to do it with no work around - changing the controls really didn't do anything. Did it upon start up and shut down. I was quoted around $350 (they checked it out when I had the car in for something else.) I was told that he was the heater core return actuator or something like that. Mine was coming from around the glovebox though. Somehow it stopped awhile back and no longer makes any noise so I'm pretty sure something broke.

 

Very informative! It DOES look like a huge PITA...
