The rear window lock on the 2000 Blazer might have gotten rusty and will not turn to unlock the window. Try spraying a lubricant like WD-40 into the door lock. Wait a few minutes and then try the key in the lock.
how to open the rear window on a 1997 chevy blazer.
Make sure the door is unlocked and pull the handle, either inside or outside, and it should open the lock. If not, use a screwdriver to pry it back open with the handle pulled all the way out or up depending on the handle.

The latch on the actuator is probably broken... it's a very common problem for the Blazer. Pull off the trim on the rear door, and you'll be able to see it (and replace it) for yourself.
The 1988 Chevrolet Blazer tailgate window motor might be bad and need to be replaced. The window motor fuse might be blown and needs to be replaced.
If one or both of the back doors do not open from the inside the child safety lock may be activated. Open the door from the outside and notice the switch in the door jamb/latch area, flip the switch to the other position.
replace/recharge the battery. either that or wrap you hand in a jacket and hulk smash the window.
you have to roll the window down and opend it from the inside. You are not supposed to opend it with the window up because it could break.
if you hold the key in the lock position it will close the window also held in the open position it will open the window
Break the window.

1992 chev blazer reartail gate window lock is broken ------------------------------------------------------------------------------------- On the 89, (83-94 S10/S15 Blazer) you turn the latch with key one direction and it opens the window. Then once the window is open, you can turn it the other direction and it opens the tailgate. On mine, the part with the "ears" started slipping. The window would still open easily with just the key. However, I was barely able to get the tailgate open using just the key. Replacement parts are available on the internet and E-Bay. You can remove the key part by removing the inside panel of the tailgate (must be open). Then 4 - 10mm bolts to hold on a cover. You may need to remove the rest of the latch mechanism (or at least push it out of the way). A slide-type clip holds the latch in place. Pry and slide the clip to the right (passenger side). The latch should come out and can be replaced. I'm trying a "repair" now. More notes later since I don't feel like trying to re-key a generic.
