Key word being "Sunroof" there....

I knew someone was gonna point that out after I wrote it. I believe you can also access the motor if you take off the trim around the door frame and pull the headliner down after that.

i usually just bump on mine when it makes the noise and it will stop, ive also heard that blowing compressed air in there would help-something about the dust building up

 

[blueflamed03]

I heard high, compressed air cleans it, helps lower the buzzing sound...<shrugs shoulders>

heard that too. worth a try before going through all the work to remove the liner and all...

AAHH! so thats what why she makes so mutch noise, the shaft is dry and needs lube!

Going to get into this project ASAP!

LOL... i never even knew what that was above my head. Figured it was for onstar or something.. Never heard mine do anything.

hey edzarr, are you sure the tapping you hear is the flapper door? that's what it sounded like to me also, but it actually was the spring for the glove box latch. it doesn't come apart so what i did was stuff some.... geez i dont even remember now but a piece of a napkin or paper or something ,you get the idea. My sanity has improved greatly since figuring this out.

not to jack this thread but i have a vibrating noise when im running my a/c but it only starts up when i have the yukon stopped with my foot on the brake. while i have my foot on the brake i can turn the a/c off and it goes away and when i turn it on it comes back. for the life of me i cant figure out whats causing it but if any of you guys know could you please feel me in. im confused.

That little fan is called the "Climate Control Aspirator" and its very easy to replace.
It takes all of about 10 minutes to replace it.

The part costs about $45. The part number is 25903301.
