Blend door actuator

[NeverSatisfied]

What’s up everyone?

I'm at a loss. Truck started blowing hot air on the driver side when the ac was turned on. After some research, came to the conclusion that the blend door actuator on the lower part of the dash needed replaced. Checked part numbers ordered a new one and replaced it. Went through two different recalibration procedures multiple times and still having the problem. I unbolted the actuator to see if either were moving while plugged in and they were. But it seems they both will turn all the way to one side (a tick farther then the registration marks) and never move from there. At a loss on what to do next. Any ideas or advice will greatly be appreciated.

The consensus here is to only use Genuine GM actuators. I can concur with that by experience.

Previous owner must’ve got lucky then because the one I took out definitely wasn’t oem

Whoever is selling those is a idiot, the diagram is wrong in the listing and the answers they give in the q&a section are wrong
return it and get a oem one

AC Delco the way to go here?

You could get away with a dorman 604-106 and save some money over a oem one since it is a easy location to swap, usually the dorman actuators are ok, some of there stuff is not so good but the actuators seem to hold up. the dorman runs about $68, the oem one is about $112

I have a dorman one in the wife's truck. It did give me trouble and I had to take it apart and reset it’s location.

I have taken both of the ones I have apart and reset the location only for them both to click all the way to one side again
