Thanks to everyone that has contributed I apologize that car repairs for a Chevy Suburban are totally off topic for the Chef Seattle blog, but I ran across this issue the day before going kayaking and saw that its apparently a major issue with Chevrolet owners Tahoe, Yukon, etc with no documented fixes. In fact, Im pretty sure this needs to be a recall issue are you listening GM. Censored Video Removal Software here.

Replaced lift gate handle the culpritMy Suburban was working just fine up until about 3 weeks ago when I noticed that my lift gate handle had broken.

It didnt help that some dealers called it a rear door handle, trunk handle or lift gate handle depending on the model year. After I got the part, installation was easy enough pop the panel, unbolt existing handle, pry off and install new handle, reattach handle wire and that was it. Or so I thought. Fast forward six hours later. Im now at REI in downtown Seattle, where Ive just purchased a brand spanking new 1. The store has closed and Im now in the garage, walking up to the burb, kayak in tow, when I point my key FOB at the car as I usually do and hit unlock. Lights flash, I hear the usual thump sound, yank the handle and nearly fall over on my ass. Chana cs35 manual us 26. I try again and realize with dread that my lift gate is stuck. Down but not defeated, I try the button to open the rear window. No luck. I spend the next 1. FOBs lock and unlock buttons, until I give up in a garage filling string of expletives as I realize my kayak and I are SOL. Luckily, I did have a friend and an incredibly helpful REI employee there, whom all pitched in and managed to jam the kayak into the Suburban through the side door. I love my Suburban for reasons like this, though Im slowly starting to hate GMC. More on this to come. Heres the Suburban with kayak inside and the lift gate panel on the floor. If you have a Suburban Tahoe Yukon in the same situation where your lift gate wont open, the only way to get it open is to pry the lift gate panel just enough to access the locking mechanism. Take a long flat head screwdriver, slip it into the top section of the panel and start pulling away. The panel is made of a flexible plastic that will bend a fair amount, so dont be afraid to put a bit of elbow into it. Seriously, I thought I was going to break my panel, but it just flexed back fine. Once you see the locking mechanism, youll want to grip the back side that moves and twist counter clockwise until the door pops open. Once youve done this, call GM customer service and tell them that their engineers should be fired for not having a manual release.

If youre lucky enough that you can open your door or maybe it doesnt lock to begin with, then its a little easier to pull off the panel. First, take a socket wrench 9mm, I think and remove the bolt under the leather handle on the inside of the door the one you pull down on when your lift gate is up. After that, insert a flat head into the space between the panel and the door and pry open. There will be around 4 or 5 contact points to disconnect. The two last things that stand in your way are plastic hinges that hold the panel to the door frame. With the lift gate open, push the panel toward the car, then spin it an entire half circle around the hinge in the picture. After that, the panel should pull right out. Now the locking mechanism should be nicely exposed. Here we see the lift gate handle at the bottom, which is connected by a tension wire to the locking mechanism. Pulling on the handle causes the wire at the top to retract toward the right, turning the locking mechanism counter clockwise. However, pulling the handle does nothing when the mechanism is in the locked position, because it doesnt engage the other tension wire tailgate release it just simply moves by itself. When the mechanism is unlocked, pulling on the handle will engage the release mechanism and pop open the door when the locking mechanism is working, that is. Here is a properly unlocked door notice that the black plastic piece on top of the copper is slid all the way to the right. View and Download Honeywell VISIONPRO 691815EFS06 operating manual online.

You can see that if you rotate the lower copper piece, that it will force the black plastic piece to turn, thus engaging the door release. Here is why your Suburban tailgate wont unlock. Ive just pressed the unlock button on my key FOB and you can see that the black plastic piece has NOT slid over to the right. This means that the door is still LOCKED as far as the mechanism is concerned. No amount of yanking on the handle will open the lift gate at this point.

Zooming in for a close up, you can really see where the problem is. Gear heads will realize this is a major problem for all sorts of reasons. First, if your door lock actuator is banging against this metal part every time you unlock your door, it will wear out the part extremely fast and youve got yourself a busted door. Second, even if you replace your actuator, youll just bust it again if it keeps ramming this part. Most importantly, the question is how this is happening to begin with My Suburban was working fine until I put in a factory replacement handle. My opinion is that the factory GM replacement was defective and not built to spec, because the tensioner was now pulling a few millimeters more than it should have, which resulted in my lift gate not closing or unlocking. While millimeters might not mean anything to GM, it means a whole lot of difference to the Joe Schmoe who wants to have a car that works. It may also be due to a small and very important spring that resets the lock back into place. Ive read a whole ton of reports about Suburban lift gates, along with Tahoes, Yukons and other GM cars failing and drivers stuck with unlockable doors. I believe this type of careless few millimeters off isnt important BS is likely to blame. Thats why some people may have locks that work only half the time, or some work after their actuators are replaced, but fail soon afterward. My two cent opinion back to fixing cars. So what we need to do, is make some space for that locking technically, unlock mechanism to engage fully. On my Suburban, this meant giving the metal tensioner just a little more slack 2mm would be all I need. First, I pushed the handle wire mechanism over to the right and then pulled out the metal ball and wire. After that, I pinched the blue wire cap and pushed it out of the metal holder. You can now see that there is a lot of visible space between the locking mechanism and the metal. Pressing lock and unlock on my key FOB easily moved the unit back and forth successfully, so I knew it wasnt a problem with the actuator. Now comes the disclaimer part.
