I'm about to replace my second blend door actuator due to it stripping the gears. I've noticed after the first replacement that when I start my truck, I can hear the blend door act trying to over-actuate the blend door. Can't describe the sound, but I know the blend door is closed and the actuator is trying to "close" it further by the way it sounds. Anyway, after doing this for about 8 months, it finally stripped the gears in the new actuator as well. My exact question is: when replacing the actuator, does it need to be aligned a certain way prior to engaging the gears between the blend door and the actuator? I've watched many vids on replacing the actuator and nobody does anything other that bolt the new act on. Any thoughts or recommendations? If I didn't explain my problem well enough, I can try to give more detail.
