Q: Blend door actuator spinning one direction

asked by on July 22, 2017

Blend air door actuator had a broke gear and needed to be replaced I've replaced it but when the connector is applied the motor spins only one direction and doesn't stop until its made two rotations.
My car has an automatic transmission.

If you plugged in the actuator before installing it then you have ruined the new one and need to replace it then install it before you connect the electrical connector. The system will then relearn the positions.
