Does anyone have this problem? Above the drivers head is a small round plastic thing inserted into the headliner. I think it's got a fan in it because mine is making a good racket. What in the heck is this thing? I can hear it when I "key-up" the truck and notice it while driving..... I think it's driving me nuts.
Must be something to do with the AUTO AC system or just there to keep the liner from soaking?

I hope that we have "all" had a Merry Christmas.

Richard, its the "aspirator" aka temp sensor for the inside air. Give it a good wack and that may quiet it down for a bit
