1999 Tahoe HVAC control module
Does anyone know what voltage range the HVAC control module sends to the mode door motor ?
My mode door motor doesnt move enough anymore, I have measured my control module output voltage and it is 5,9 - 7 V with car idling.
When I try the motor in bench and feeds it with 10 V it moves 1/4 turn, so I am thinking my control module is broken.
Before I replace it I would like to know what voltage someonelse have at the mode door motor connection.
Could someone please help me ?
Regards Pinch
