Let''s get specific here. If your electric release has quit working but still makes a sound like it''s trying, the plastic servo arm probably snapped. I have had and FIXED this problem. I have a 2001 Blazer with separate liftglass and tailgate. You must first remove the inside tailgate handle (2 screws) and pull the center latch bulge of the tailgate trim back about 3 inches to gain access to the latch linkage. The center bulge of the trim panel is held by a tab of plastic and a screw. The tab will partially break off, but it is not outwardly visible and you can reattach securely later with an overlapping washer or metal strap piece under the screw.

Push on the linkage rods with a long screwdriver. My photo shows the best one to push on, the curved rod several inches below the latch. A mirror and flashlight may help spot it. This will release the glass! Reward yourself with a cold one.

Then open the tailgate and remove remaining screws holding on the plastic trim panel and the metal panel just underneath it. There is one linkage rod attached to the inside of the metal panel that must be released at its plastic gromment before turning the metal panel upside down. The servo is attached to the back of the metal panel. See photo. Replace the servo arm (dealer $60 for arm and servo I read, or Rockauto.com about $10 for arm only) or repair the arm. My repair is going strong after almost 2 years. See photo. Good luck with your repairs!
