Suburban rear lift glass wont work

[02suburbanZ71]

As long as i've had this suburban the rear lift glass wont open but the cargo door will. Your supposed to unlock the vehicle and press the button and it will open. When i press my button it goes it, gets stuck and will not release the glass or button and the button gets stuck. The actuator works i believe because i can hear it lock and unlock also when i lock/unlock i can feel it move the button. Using a key will not make a difference. It opened yesterday for the first time ever but once i shut it, it would not reopen

This is a manual lift, what do you mean it won't reopen. Once the key locking mechanism is unlocked, it's then pressed and the lift glass disengages. After that it's all about pulling up on the glass about halfway then the adjuster takes it the rest of the way. If it doesn't work like that then the key locking mechanism may need to be replaced, sounds like it may not be disengaging the glass. This was a great year for Chevy, but actuator or tumbler could have rusted or worn-out, this is a thirteen year old vehicle (if your talking about your '02).

Yeah once its unlocked and i press the button the glass wont disengage

Took a look today, the button is a simple manual operation. When you press the button, it causes a spring to pull a lever which kicks-out the glass. Looks like you may have to take off the weatherstripping and possibly the liftgate panel to replace parts, may be more hassle to fix. I have a shop manual somewhere, it should show how to remove the liftgate panel. If the glass unlocks, it can open, you just have to pry it. This won't fix your problem, only get the glass open on this occasion.

Im so tired of problems with this suburban

I have a 2008 Suburban. The release button is electronic, I believe, but it does NOTHING. From what I've read, the only way to remove the panel from the liftgate is to open the glass and remove the screws. If I can't open the glass, how can I remove the screws that hold the panel that covers the locking mechanism?

The rear wiper doesn't operate either. I don't know how to get to the wiring without being able to remove the liftgate panel.
