Re: ? motor running noise in dash

Some of the 2000 and up trucks have a small deal just above your head in the headliner that just may be the source of your noise. My 06 crewcab and 03 Tahoe both have these and both make a sort of buzzing noise. Real noticeable when the radio is turned down. It stops when the key is turned off. I think I was told it is a small blower/sensor deal for the climate control or something.
