Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is***** for the question. Can you tell me what position the more stays in? What vents does the air come from?
Does the actuator make and noise or attempt to work even a little when you try changing the mode?
You need to check the voltage between the brown wire and the tan wire. While moving the more knob the voltage should vary. The other wires are positional sensor signals. Typically where he issue lies is in the fuse box under the right side of the dash. There is more than likely a bad connection or a short in that area causing this. If not then it may be the module is defective.
Sounds good. I will look for your response then. If I am not online when you return I will get back with you as soon as I can.
Did you happen to remove the connection at the fuse box to see if the terminals in the connector were loose at all?>
Did you try clearing the code to see if it would come back or if the system would work?
If you check the voltage of each wire separately at the actuator and see if any of them vary while moving the adjustment what do you get?
