Driver side is acting up, blowing hot all the time pulled cover under dash and located Servo with a tap or too started working again. Am getting 0 to 5 volts
From controller so it seems to be motor !? Local Chevy dealer parts counter
Is a joke last time they gave me a schematic

Can you remove the servo and take it to the dealer to purchase a new part?

These seem to have a limited life span with automatic climate controlled models. I usually grab them online and not from the dealer.

Only way to fix is replace them when they go bad. My dash rattles and clunks all the time when the HVAC is on. Annoying.
