acc growl during startup
Hi all,
When I start my 07, I almost always get a growling noise in the acc for a few seconds. It only seems to happen when I have the auto climate control already on when I start my truck. Any ideas?
Thanks

hi there,
the acc is controlled by little servo motors that open and close the baffles that controll the air and temperature, my 04 does it a little but i always make sure that i turn the heater/ac off before i shut the engine off. a little noise is ok, but if you can hear them over the radio or blower, there could be a problem with them
