Rear lift gate woes

[5strmtrp]

Finally got a few things tackled on the SSV. Running a bit better with less stumble now that it has new plugs n wires.

This week I took my wife to the airport at an ungodly hour and found out that the rear lift gate wouldn’t open. The glass pops open but the gate wouldn’t open.

Figured it was possibly a fuse but, hark today it opens. Removed the whole inner panel and see nothing out of the ordinary. It’s definitely been lubed up in its like as there’s a lot of grease goo in there. Cleaned it up but it’s still sporadically working.

Any suggestions? Been looking on rock auto for a replacement switch do dad but not sure if that’s what needs to be replaced.

Anyone have similar symptoms issues, feedback always welcome.

Thanks

Well here I go again, if you have a Tech-2 or other bi-directional scan tool, you can test the tailgate and see the internal trouble codes as to why it is not working. There is a dimple on the interior panel and if you drill that out with a 1-1/8" hole saw, you can use a screwdriver to manually open the rear door from the inside. There is no mechanical latch external. GM sells a plug to cover this hole for the next time you need it, 15836140 (ebony). Stick with GM OE or ACDelco Professional parts.

The new Corvette and 2021 SUVs went this way all around.

Thank you,

I really need to get a tech2 or similar. It’s been on my list, just need to research which candy module I need. Have 3 GM vehicles from 2007 to 2017 you would of figured I would of done this by now.

Well, you might want something else, like the MDI with GDS software (or MDI2 w/GDS2 software) which can talk to your new cars as well via a laptop. I like the handiness of the Tech-2 and Wes figured out a way to use the VXDIAG NANO wireless to talk a Dell tablet and use GDS and Tech2Win software for both old and new and costs less.

They gotta get you on the payroll James. The “button” on the outside goes bad and double check the wires coming in through the top.

Your referring to the entire harness that’s coming from the roof area of the truck and into the tailgate behind the 3rd /center brake lamp?

Ive had to silicone the cover that attaches to the body into place. It was broken and was letting water into the truck.

I’ve been told, have to look it up on gm parts that the harness is expensive.

I wish there was more of these body styles available in the salvage yards!

Ok your talking foreign language to me!! Lol, but I’m interested in seeing how it works. To whom do I contact? Having GM cars/trucks from 2007 to 2017 would be awesome to be able to do stuff like this.

Yes but not necessarily the entire harness. The wires get frayed so you’re just looking for that.

you can use a tech2 on your xx-14 suv's in 2014 gm switched over to GDS2 but I have read you can still use the tech2 for 2014 suv's but I haven't tried it on a 14 yet.
you can get a little electronic obd device online called a vx diag nano, it runs via usb on a windows laptop or tablet and it will give you tech2win (software based tool) and GDS2 for the 14+
the vx diag runs about $100-125 works on 07-14, and 14-current with gds2
~versus~
a clone tech2 (tool) runs about $300
a gds2 based (tool) runs $1200+
~versus~
a trip to the dealer for a diagnostic is $100 a pop

I have to get the friggin gate to open first. I saw that there’s a way to open the buggered from the inside.

I’m thinking there’s frayed wires as You mentioned. This rig came with a back up camera. That also works when it wants.

I’ve got a Scout trip in 2 weeks that I need the gate to work. Camping gear my backpack food cooler and the chuck box all go in the back. Dammit need a 30 hour day, this 24 hour isn’t working!!! Lol

look on the inside panel, you will see a dimple spot, drill right there thru the plastic cover then you can poke inside with a screw driver and pop the latch open, once you have it fixed the hole can be capped off with a plastic clip

This dimple spot that your referring to. I’m not seeing it, then again I’ve been on call for the past 36 hours.

It’s to the drivers side of the latch assembly.

If you use a 1-1/8" hole saw, GM sells a plug that covers it right up. Just did mine the other day, before it breaks!
