I just like how it drives, and for being at 150k miles it’s really been super reliable. Very few issues.

I now understand the drama. Easy, with my wife of 35yrs as a passenger, turn the heat to max, then open the sunroof and ds window.

Chevy dealer here can’t get the actuators. Does anyone have the diagram that shows all of them? Are they really all diff part numbers? Orieley can get them but they’ve only got one part number.

thank you. I’m not very mechanically inclined, so I appreciate your help! If I’m reading this right the same one can be used for the temp and mode actuators? I figure I’ll start there. I used to have a diagram saved that showed where each was mounted but I can’t find that.

Thank you so much! So if I’m looking at the diagram properly then I can use the same part for all 3 of the doors on the driver side?

Read the description on RA I posted above. Recirc-x1 blend door & mode door x3. Did you want me to install them for you too?

i did read them.

. So in a left side driver there are 3 actuators mounted on the driver side that you can get near the steering column. Those are 2 air controllers (for right and left), and one mode controller. If my understanding is correct all 3 of those are the same part number. The fourth actuator for circulation is harder to get to and is the other part number. Again, if I am reading it all right.

if you ever need computer fixes I am your guy. Cars not so much. 🤷🏻‍♂️
