Same exact problem on an 03 Yukon. Took the actuator off and the door end fell into the box. I have a membership with Identifix, and I didn't see one repair where this was the cause.

Thanks alot. I just checked mines out and it is the actual blend door, and the actuator. The actuator twisted the door to high and I'm assuming that what broke it. I'm gonna head to a local junk yard to see if I find the pieces and gain more experience disassembling another ones in case I miss or break something I learn from it.

This was a great video as I had the same problem. If you want to take the whole thing out there are two 10mm nuts, two 13mm bolts, and two plastic clips for the heater core under the car. If you take those out and the two screws inside the entire assembly will come out of the car. If you do this you will have to recharge your AC and will lose some coolant. The hard part is the plastic parts of the heater core as they get brittle over time.

Do you know the part number for the blend door? Mine is broken just like yours in the video. I was able to prop it into place, but want to fix it. I found part number 902-321, but on the installation instructions on one site it says its for the front.

Rear blend door actuator is part # 604-111. That is an aftermarket part # and is the easiest place to start trouble shooting. If you take the old one off and start the car you should be able to change the temperature coming out of the rear vents from hot to cold by turning it manually. If the temps do not change then you have a broken door

@@snorider22 Thanks for the response. It was/is the door that is broken. I cant seem to find the part # for the door. I was able to reach in and move it so it puts out heat and because of this I only use the rear air when its cold outside.

I have temporarily fixed my broken blender door with a paper clip. I removed the heater to access the door, then I took a paper clip and bent it into a hook to hold the door shut and the other end a hook to dig into the foam to hold it in place. Hopefully I'm able to afford a new evap case by winter. Thanks for the video and others comments! My 2yo is finally riding in comfort again.

I just did this job on a 2005 Yukon Denali and it wasn't too bad. I'll give some tips that I used in order to complement your video. That bottom screw came out easily with an 8mm ratcheting wrench. Getting back in was a little tougher. I left the two screws, that anchor the top of the unit to the body, loose to give a little wiggle room. I got the screw started by holding it on the threads with a pair of needle-nose pliers in my right hand. Then with my left index finger, I held the screw in place while using the pliers to turn the screw to get it started, then used the ratchet wrench to button it up the rest of the way. During installation of the new unit, I left the blower motor out and was able to reach through the hole to put the rear two clips back in. For the front-rear clip, I had to pull the unit towards me as much as possible then reach down from the top to put the clip in. It was pretty much a blind pass trying to hold onto the clip while feeling for the holes it seats in. If you look at the placement of the clip on the front side then draw an imaginary line to the rear, you'll be right where you need to be. I had a little trouble getting the actuator motor in the middle of the housing to line up with the blend door end that inserts into the actuator motor. The motor travels further than it should when there is no blend door attached. I solved this by attaching the actuator to the wiring harness then turned the ignition switch to the on position and ran to the back. While watching the actuator motor turn, I waited until the two position indicator notches lined up then unplugged it. Worked like a charm. The front actuator was already lined up well and didn't need any adjusting tricks. While I was in there, I blew some compressed air through the heater and evaporator cores to clean out any dust but they were surprisingly clean. Hope this helps.

Thank you for the awesome post/video. My 2004 Tahoe has the exact same failure mode, the shaft on the blend door broke, the break looks exactly like the one in this video. What was the trick in getting those clips removed and re-secured in the rear, and also how did you get that tricky screw by the wheel-well back in? Thanks. Part # for the case/housing for my model Tahoe is #88891577. That's a 2004 Z71 5.3L SFI, 8 cyl, T VIN, auto a/c control, 3 zones - 2 in front, 1 in rear.

Same exact issue for me too. It's possible to remove the door/flap (white clip will release the door/flap on the back of the housing) I manually put the door in the A/C position and removed the actuator until I source a replacement. No real rush now, since I'm good until winter. The GM part # is 12477711 and it's called an "air conditioning evaporator core housing".
