2004 Chevrolet Avalanche Repair Question
Chevy ac coming out of defrost vents only
2004 Chevy Avalanche V8 Four Wheel Drive Automatic 68000 miles
yesterday, i replaced my battery. now, my ac only blows out of my defrost vents. why?
first thing to do is pull the hvac fuse for 30 seconds then see if the heater module will reprogram itself. If not the picture that has #1 marked on it is the actuator and that may be stuck or no power coming ot it. see if you can play with it to unstick it.
