I have a 1999 Blazer. I need to get the inside panel off the hatchback off. I have not destroyed it yet. There is 3 screws behind the glass. The lock will not disengage to lift the glass so I can get to the screws? Any hints. Thanks

 

Check the fuse panel under the hood. Look for the 3amp fuse. even if it looks good replace it.

 

If I remember the rear trim on my old Bravada with the full liftgate (assume that is what you are describing by saying hatchback), there was only the one screw at the window. If you are careful, the plastic near the screw can be broken in such a way that it can be reassembled without even knowing. After that, there is a whole bunch of spring clips and I think only one other screw at the pull handle.
