Rear passenger side panel, where all the working stuff is for rear HVAC.
Thx @Fless. Do I just mess with the flap inside? Or are they just cheap enough? My ac isn't that great at idle--clutch fan. It actually wasn't that cold today while driving for some reason, it was cool. I just had it charged too.

Not a clue, never had to open mine up. Surely someone here has. Bet there's a bunch of YouTubes on it, though.
I opened mine up, because it had a hole in the side from the damper breaking off, thus leaving a hole. I epoxied the damper back together, but that clamshell is a MFER to get back together correctly in the rig. I purchased a new one, since mine’s been half assed assembled ever since (2.5 years ago), and I’m confident the plastic has bent incorrectly, due to my shotty reassembly job. (And yes, the new clamshell is still sitting pristine in it’s only-opened-to-verify-contents box… [emoji23]

It’s OEM, and was pretty well priced. I think around $100. I do believe I ordered from The jungle site.. lessee….

Nope, was not a Jungle site order. It must’ve been one of the halfway decent GM Dealerships, who sell online. Sorry I don’t have the specifics. I’ll have to look at the box. Sheesh T, now I have to go all the way out and look in the shed..!

It appears this will require further investigation…

What's that? I know what a clam is ;)
the up/down actuator is the one at the Y in the air housing when you remove the cover there are 2 actuators, the one closest to the blower motor is hot/cold, then up forward at the Y you will see the pipe go up towards the roof and down towards the floor that is where the second one is located.

Thx Wes. It's been hell hot here--low to mid 90's, so it's too damn hot for me to even mess with anything. Supposed to cool down later in the week, so hopefully I'll be able to look then.

Does anyone know where the actuator is for the roof vents? I tried resetting the hvac using the tech2, still blowing out warm/hot air.

i changed that actuator, its under the plastic pass side rear. i did that module first and it did nothing. actuator was the fix. and i got to say, working rear ac helps cool the truck down a lot faster.

I need to revisit mine. I think I replaced the blend door actuator back there a couple years ago but now the mode one is acting up. Whichever the one is that controls if it’s on heat or ac..that’s what’s acting up now so I just leave it turned off.

if it is blowing out warm air then you want to check the actuator closest to the blower motor, all the other actuator does is send it up or down or in the middle, doesn't control temp.

I picked this thing up for work a few weeks ago. Been keeping me busy and my mod money tied up! Love the 2.0Turbo in it. Probably going to park it and drive the tahoe anyways. I dont like the miles climbing up closer to 27K. Tahoe cluster is broken so what I can't see can't hurt me or don't exist!! I just pretend she doesn't have well over 240k miles. She still my baby!! I need to post up pictures of my shorties. Looks good in the bays.

Anyone know of the top of the dome which OEM plug wires facilitate more room around exhaust manifolds??? Probably going to add some new AC Delco iridium plugs and new wires just cause on the tahoe.
