? motor running noise in dash
Got a '01 Suburban 2500 6.0...when the key is on, I can hear some type of small motor running. It's not real loud but noticeable. Sounds kind of like heater/ac blower motor, but does it even when that is all turned off. Seems to be coming from somewhere around center of dash.
Just curious as to what this sound is?

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.

Re: ? motor running noise in dash
It's normal. There are something like 8 motors in the dash. They cycle when key is turned on. Regardless if heat is on or off

Re: ? motor running noise in dash
What about a thumping sound? At times, the dash in my 05 sounds like it has critters thumping around in it.
