I need to replace all 4 of my trucks actuators, however I can't determine if they are different part number's since they are all called "blend door" actuators.
Do you
have the same problem?

I was replacing my mode door actuator and inadvertently pulled the (for lack of a better term) "guide plate" out with it that controls where the air is directed when the actuator moves. I cannot find any information anywhere on how to realign everything when reinstalling the actuator/plate. Help! I am short on time!

Thanks. While waiting for a response, I crammed myself under the dash and fiddled with it. I am not sure I could do it a second time, but I actually got it in correctly by accident, lol. A bit of advice for anyone else that was stuck in my predicament without plugging in the wires to the new actuator, you can turn the car/truck on and turn your fan on high. Then turn the dial on the controls to the defrost option and reach under the dash to manually manipulate the gear/door so that it directs air through the defrost. The moving air will hold it in place allowing you to (hopefully) fit the new actuator and guide plate in correctly and (again hopefully) aligned. Anyway, that worked for me.

I am looking for a way to put on the actuator, but I cannot find the mounting bracket.

There is no bracket. There will be three small elevated plastic areas with threaded holes.

The holes so not line up but there is a 14 difference between the actuator and the blower box. The Chevrolet place says the mounting bracket is discontinued.

Then I guess the only option you have left is to find one in a U-pull-it junkyard. I am sure you will have to remove it yourself because the yard will not be bothered with something like that.
