HVAC Mode Actuator

Thanks for the reply, Joe, used an aftermarket part. Did not check the door manually. It did work well for about a month. I used a 9v battery to align the gear on the actuator prior to installing it. Hope that didn't mess it up.

It is a Dorman part bought from AutoZone. I'll buy one from the local Ford dealer. I didn't do that originally because I had read they were defective. Other than aligning the gear, is there any calibrating or resetting the HVAC that needs to be done after installing? Thank you.

Hi Joe, pulled the Dorman actuator out and found the spline had separated from the gear. The spline stayed in the airbox when I pulled the actuator. Looks like it snaps in and has a little slot it fits into. You could see breakout in that slot allowing the spline to spin inside the gear. Manually moved the door through all modes. It was a little stiff in defrost but got easier as it moved towards the vent. Installed the Ford actuator and cycled it through all modes. Everything's quiet and working again. Hopefully it stays that way! Hope the door isn't too stiff causing the actuator to break. I really don't want to change out the airbox! Thanks for all the help. Let me know if you think there is something else, I need to do.
