I posted this problem on the other site but got no real help. At times I hear a repeating grinding noise that seems to be coming from behind the center air vents. When I turn off the climate control it stops. A GM mechanic said it might be an actuator but when it was in the shop they couldnt reproduce it. It doesnt seem to occur at any regular interval, just random times. And it will occur for a couple minutes then stop while the ac is still on. Any ideas what this might be? I actually recorded it on my cell phone but the file is too big to zip and upload to the forum.

I'll take a look. I used to have a website that had parts breakouts for every part of my envoy but it was closed. Do you know of any websites like this?

The site I used to use had diagrams of the parts and their part numbers. The site you sent just tells me to call them to find the parts I need.

That old resource was compnine.com, and the world is the worse off that they closed shop. Everybody used them for the diagrams and part numbers and almost nobody bought their items there because they were offered at list price. Like the way Best Buy is being abused as the free lookin'-at store for stuff people end up buying from Amazon. 
There are exploded parts diagrams I snagged from compnine and photoshopped along the way, but not nearly all of them. This one may be useful:

Wherever I go, that picture follows.
