Power Lift gate problem.....Help

[Chilidawg]

I bought my 2010 yukon in April 2013, when I started going through old receipts from the previous owner, I discovered that the power lift gate has been an issue since new. The latch had been replaced three times and the module once. I stated having trouble about a month after I bought the truck. At first it would partially unlatch but I was able to open the gate by hand and it would work again then later it would stop working for days. In the year I've owned the truck it has been in for service six times for the lift gate at a total cost of almost $1500. They have changed the latch, shake test the wiring and recalibrated the liftgate. The new latch is acting up after five weeks. This morning I opened the liftgate and it started bobbing like it didn't know which direction to go in.

The sales manager has offered to take back the truck and find me a new one, we just have to work out the details. I use the cargo area on a daily basis and I just don't feel confident in this vehicle anymore.

Motor works...but gate stops halfway and closes again.

Ok.....I have a 2007 with 165,000 miles on it. Runs perfect. Last 2 days the lift gate when trying to open it, would open halfway, then close. If I tried opening it by hand, same thing. Motor and remote appear to be functioning ok, just the gate seems like it's hanging up on something opening.

Needs new struts. 20 bucks a piece online. Like 40 from the dealer or autozone.

My father-in-law has a 2007 Suburban that has had an inoperable power liftgate for about 4 years. First, it wouldn't open automatically any more and only make noises, but it would still latch. About 4 months ago, the latch failed and the door opened on the highway, so he tied the door closed. For a Christmas gift, I bought him a new door latch and struts installed them (upon inspection, old struts were still good). The door will now open with any method (overhead console button, remote, or door handle) lights blink 3 times and chime sounds. The door will unlatch and fully open properly. I can hear the motor running. If you press the button or remote, the lights blink once and the latch makes about 10 seconds of noises, but the door does not move. If you close the door manually about a foot, the latch makes the same 10 seconds of noises, but the motor does not run. I have checked all the harness from the headliner to all door components, but none appear damaged (as per the GM TSB). Is there a liftgate relay, because it appears to not be reversing the polarity of the motor to close it. There is a microswitch on the motor gears that engages the closing and opening of the door when it is about 3/4, because when I manually close the door and the microswitch engages, the latch begins to reset and make noise, but the motor does not run to close the door. Once manually closed, the door latches properly with about 10 seconds of noises (probably because the door timing is off and the BCM realizes the motor is not running in reverse) I do not have access to a Tech II scanner to run the GM diagnostics. From all the posts that I have read, the motors do not go bad and replacing them does not solve things. It has always been a problem with the latch. A liftgate wiring diagram for a 2007 LTZ would be very helpfull as would any suggestions. Many thanks!

So my 08 Tahoe LTZ is doing the only open about 1/3 of the way and close(with the remote)...common issue I gather.

I have the power lift gate turned off and just open it up the old way.

My latch is making all the noise and I have replaced the struts with new OEM replacements.

Now I just pulled the latch out and the part number is 15839037, I guess I will order a new GM part and call it a day.

Well apparently my truck was still on the original power lift gate latch, because the part number shows that it has been replaced with another part number:

Part No. 15839037
Part Description LATCH
Replaced By 13502698

My module died a month ago. Got a new one and installed it. Hope it holds out a while on other parts

 

[1BADI5]

Well the dealer had the part on hand.

The revised part number is NOW: GM#13581405

The list price was $273.50
My price was $205.12, they give me the shop price since I buy alot of parts from them

Easy project, spent more time pulling the plastics out then installing the latch.

My 2007 Denali started this also in the last few days. Hit button and makes noise like latch is unlocking and does not go up. Pull it open manually after it unlocks and the door will stay up. So not thinking struts. Took lift rod off and motor only acts like it is trying to move. Anyone else have this issue and what did it turn out to be? Thanks.

Hey folks! My 2008 Yukon's power lift gate latch stopped working suddenly. It will not latch when i manually close the door. Pressing the power close button while the gate is up will get the latch to make noise for a few secs but the gate won't move. Any idea whats going on? Basically two issues, i just don't see how they can be related, unless this is one hell of a coincidence for both the latch and the motor that opens and cloases the gate to go out. Appreciate any input!

Similar issue, I was able to lossen the interior panel while the liftgate was stuck closed; unplugged the switch and used a jumper to force the latch to open

seems to be working now but I did leave the panel off as I expect the problem to return

The button inside the handle hasnt worked since the day we bought it and we had to use the fob to open and close the gate. Has any experienced this exterior button issue?

2010 Tahoe

My interior button wouldn;t open it also, I just put a new latch in and crossed my fingers and pushed the botton on the liftgate and bamm it works. The remote and the interior switch all work to open close the gate. Glad I did it myself and not the dealer. Tool all of 25 minutes.

There is a switch up on the overhead console, by the moonroof switches. It can be flipped to deactivate the power lift gate. Make sure that didn't accidentally get flipped. It happened to me once, must have been the wife poking away at buttons.

Ok, so this happened to us too. Somehow one of us inadvertently hit the off button to the power liftgate at the airport and we had to open the gate manually. We thought something had broken. Thanks for the tip, problem solved.

2007 Chevy Suburban LTZ...Back hatch will lift but wont come down. It makes noises but wont do nothing if its all the way up. Now you can lift it midway and repress button and it will shut. After reading all these post im guessing the latch is bad. Thanks in advance!

I have a 2011 Yukon and just replaced the latch motor. It works great except every now and then when I close it automatically it will open back up on its own. It does this when it’s almost closed. Can anyone help or suggest what to do. Thanx

2008 Yukon Denali - Power lift gate will not open or close with FOB or overhead switch. No sound, no lights flash, nothing. Will open with manual button on liftgate handle. The FOB opens the glass hatch. Any ideas?
