Rear glass will not open

[Playsinsnow]

So yesterday the gremlins were out in my garage, first time something's up with both rides

Now I just need to get the rear glass to open. When I push the cylinder in to open the rear glass, it feels as if it is locked. If I lock the doors and unlock them it will open, only the first time. Once I close it it will not (so not a huge issue, yet) even when still unlocked.

I never slam my glass and always push it til the click. I use it just about daily. Problem is I don't have time until next weekend to tear into it. Any idea what I'm looking at? Replace the lock cylinder? Simple fix or...? I can't search the old site and haven't seen anything here, yet. Thanks!

The linkage from the unlock solenoid could need some lubrication. Pull the inside paneling off and spray in the places that seem like they're solenoid or linkage-related. Sorry I don't have pics.

Ahhhh, but I found some in a short search

Thanks roadie! I just came across that too. I searched "rear glass" and was caught reading unrelated material when told I better be ready to go soon! Im ready now and just might be able to spray it before she comes out...

Old thread but the rear glass push button would not open again. Felt like it was locked after cycling the fob locked/unlocked several times. WD40 on the push button freed it up the first time. This time I had to get inside. Without being able to take the trim off because the glass would not open, I simply saw the black rail in picture "wanting" to go up on unlock. Popped it up ~1/4 inch and felt like it did something. Checked rear push button and the glass opened. I'm posting this picture so if anyone can not get their rear glass "unlocked", pop the small cap at the bottom of the panel, stick your finger in and lift up. Assuming linkages are still connected.

I've had that problem a couple times. The first time it was just the pivot at the top that was sticking. Second time it was the actual latch mechanism that was all frozen from rust and corrosion. To really fix it I ended up having to pull the entire latch assembly out of the liftgate, soak the thing in PB blaster to break up the rust, then after spraying it with cleaner to get the residue off I soaked it with lubricant.

FYI - you can get the trim panels off without opening the glass. I never opened the glass to take mine off since I have the liftgate open when removing them.

I was about to post this too, then I remembered, there's a screw at the top of the main panel, that's accessed from next to the glass' latch. On my truck that screw is missing, so it's not a big deal. Not sure if that's a LWB only thing or not.

The SWB have it too. IIRC it was just a plastic trim button. Mine never made it back on after the first time I removed the panel.

Oh. Mine apparently is missing as I've never messed with that lol

Only had my TB for a couple months and always opened the liftgate when loading the cargo area so I hadn't noticed that my glass wouldn't open until recently. In fact, the button sits flush with the housing so I'm thinking I'll have to go at it like Sparky described above.
