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).

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.

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.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
