When I set the hot/cold **** to full heat, or full cold there is no sound. But any position between full heat or full cold i hear a slight click or knock. It doesn't matter what setting it's on, floor, vents, defrost etc. I've read up on the blend actuator motor and I'm leaning toward it, just want some verification. Anyone with good links, videos or success stories let me know. I'll get a video tmw of what I'm talking about....

 

Ha Just posted about this yesterday. I got the same thing

 

Yea that's the noise! I just watched a video on YouTube about the tsb and the guy replaced his blend door motor, here's the link....

 

bad blend door motor, ive had 3 installed under warranty.

 

What does the blend motor actually do. Because I still get hot and cold...

 

Yea I still get normal hot/cold operation, mine just makes noise... It's quiet if its on full heat or full cold. Here's a video...
