Hello, I have a 6 pin blend door actuator motor, but my harness is 3 pin.
just looking to get a part number for the actuator. its looking old, but I want to get the right one. Can't even read any numbers on it.

Thanks

 

There are generally two types; one for the Computer Climate Control (auto HVAC) and the manual one. For the auto one, you will have a dial that has the temperature set point on it.

As for the part numbers, I like going to the GM parts sellers online where you can enter in your vehicle type and sometimes you VIN then you can get the correct part number. Then with it in hand, you can shop around for what you want as generally, the GM sites will have higher prices than elsewhere.

Good Luck
