2009 Chevrolet Silverado 1500 air doesn’t come out on floor

Air does not come out on floor

Failed blend door actuator.


The blend door actuator is for temperature control

If anything, the mode door actuator may be at fault

however . . . if op managed to somehow drop a few pens, paper clips, etc. into the plenum, that could prevent the mode door from having full range of travel

You are correct, I should have just said one of the HVAC system actuators has failed.

I just noticed something . . . on Rockauto, at least

They refer to all of the hvac actuator motors as “blend door actuators” . . . but then in the description, it states what they individually control

I could see somebody ordering the incorrect part, if they don’t carefully read the “fine print”

I brought this up, because this isn’t the first time I’ve heard other people refer to any and/or all of the hvac actuators as “blend door actuators”

Actually it’s the mode door actuator.
