Guys,

I have a 2005 Tahoe Z71, automatic rear air and heat. last winter I had no heat. I took it apart and as a quick fix I moved the heat/air door to heat for the winter. I got back into it this weekend and with intentions of fixing it since I had more time. I swapped the air/heat actuator with the upper /lower vent actuator and the problem followed the actuator. Great, problem fixed, get a new actuator. Problem is is the descriptions dont make sense to me. the one that I think it is is a Dorman 604-100. Problem with that it is a four pin connector, the one that failed is a 2 pin then a space then a 3 pin. Does anyone know the correct part number for a rear heat/air actuator? Dorman or GM part number?


Thanks,
Scott

 

Welcome to the forum.

Might try gmpartsdirect or your friendly Chevy parts man.

 

Rock Auto appears to have quite the listing of parts and part numbers see if any of these fit the bill....
