Hey Matt! great to see Tahiti again. I wanted to let you know that I noticed when you were opening and closing the whole hatch after the new struts, I could see the window glass actually bounce open a bit! I got worried and wanted to let you know before it might accidentally break from the movement.

I have an 07 that I bought several years ago and am now floating near 300k miles with stock valve and drivetrains. It is tuned as well as the trans but although she’s starting to rust in the normal tahoe spots, she’s still more reliable and valuable to me than my 2011 Mercedes e350. The tahoe line has it’s flaws but man they are damn good trucks, I can’t justify replacing mine.

I’d start with the quickest and easiest diag of using a dmm on the blend door motor connector to see if you are getting the signal from the hvac unit when the recirc button is pressed. It’ll cut the system in half to start looking at wiring and triggers to the motor or to know if it is a mechanical out of limit issue from the blend door seal defeating and causing it to move further than expected.

Matt, I'm back in a suburban after trading my Yukon xl and I missed these trucks. I have a code reader you definitely need to pick up. It's the Innova 5510 at advance. It was on sale and there's a coupon code on their site. I paid 187$ for it and it's the best code reader you can buy short of the high end ones. It scans every module in your vehicles and it scans HVAC and door modules and all that stuff on my 04 Suburban. I've had tons of code readers but this one for the money you can't beat it. If I can copy the link I will for you in the comments.

It’s normally the hvac control unit, it glitches out and maxes the blend door motors beyond their limits for some reason and ruins them. Happened to the rear hvac controls on my 03 Yukon, it maxed out the temp control blend door motor. I replaced just the blend door motor and left the old hvac computer, it maxed it out again and ruined it. I replaced the blend door motor again and the hvac unit, and it works perfectly now. If you do replace the control unit do not buy a used one from a junkyard it most likely has the same glitch in it, definitely get a new unit from dorman etc. The new control units have the glitches programmed out.

Hey Matt glad you're back! I know your pain with the vent doors not working properly. I had a similar issue with mine except it would make a popping noise for exactly 30 seconds at each turn on. I did some experimenting with the standard recalibration steps and found a way to get it working again although my dumbass didn't write down how exactly I did it. So maybe try playing around with the fuse-pulling pattern, timing, etc. and maybe this will work? Best of luck to you, I'm literally scared to disconnect my battery now!!!

So - if my door is exactly like yours it's stuck on non recirculation? I guess I can live with that as I don't live in a very hot climate. Unless there is an easy fix. I suspect the foam weather stripping has worn away and the door is over traveling and setting a dtc. Since you have yours all apart, you can drill a hole in your actuator and put a small machine screw and nut to serve as a new stop and keep the actuator from over traveling. For others like me if we can find some way to put a stop on the door to keep it from closing that last 1/16 of an inch it should solve it.

This is one time where the original Wiring Diagrams will answer many questions. There is no replacement for the correct information. If it's anything like a Ford EATC climate control system's Blend Door Actuator, it's a reversing DC motor with a Potentiometer for position feedback to the Control Box. Mazda used the exact same setup on the Eunos Cosmo (Japan only) for all of its HVAC motors. I would wager that it is a harness issue, either 12v+ or Ground being incorrectly fed into the system so it knee-jerks to Fresh Air and won't budge otherwise. The nice thing is that you can bench test each component before digging into it again.

Does anyone else have the issue where the rear A/C doesn't work unless the front A/C is also on, just curious if thats the way it's suppose to be or if there is something wrong with mine? I already did all the upgrades on it from next generation front bigger brakes, to E-fan conversion with oem harness, transgo HD shift kit, added big trans cooler. Also installed new power steering pump and steering box, rebuilt front end, new fuel pump, hoses, belt, spark plugs and wires, serviced all fluids and filters, installed bilstein 5100 series shocks and new rear springs and more. It has a little over 200k on it and still runs strong, this truck is now ready for another 100k. I love this truck and don't think I will ever get rid of it.
