One of the HVAC door gears was stripped and needed to be replaced. Because of the location it’s hard to tell what the proper alignment should be when I replaced them. Do you have a diagram showing me the positions of the gears when installed? The proper alignment so the defrost works.

Yes, the gear has a little notch on it so that must be aligned with pivot gear. Here is a diagram to help with the repair. Check out the images (below). Let us know what you find.
