Hvac problem
I have a 2007 silverado new body style and my air only comes out the top vent have tried replacing both the servo and controller. I can get the vent to work manually by moving it by hand. I checked it have good power and ground going to servo and it goes through a starting sequence but just goes strait the top vent after. Is anyone else having this problem?
