#1 of 1 Rear air fans activate when not turned on. by lness Oct 26, 2008 (11:47 am)
2004 Chevy Trailblazer EXT. There is a knob on the center console that allows the driver to set the fans speed for the rear passengers (3,2,1,0,R). "R" is for rear and gives control to the fan speed dial on the back of the console so the passenger can reach now and set it. Recently when accelerating (intermittenly) I can hear the rear vents going at full speed. The drivers knob is set to "0". After a short time, the air stops blowing as fast, but it seems like it's on "1". I reached down and dialed the know to "3" and the back to "0" and the air shuts off completely as it should have been in the first place. Does this sound like a problem at the Dialing switch or is something evil a foot.
