my rear door latch is busted. My 3.4 is partially in. I forget if pushing the rear window button on the 86 jimmy pops the window? the battery and accessories are not hooked up yet so i can't pop the button. Is the another way i can open the rear gate? thanks

other than using a key, or hitting the button, your kinda screwed. You could try wiring the switch to battery (direct). Or depending on the style of the latch, you can unbolt it from the window, and remove the handle. That should let you open the glass. But the "U" hook will still be locked in the door so you won't be able lower the tailgate.
You can open your tailgate but first you do have to open the window. Then all it takes is a large screwdriver to turn the lock mechanism on the inside. If you can't get the window open use a medium size flat tip to push the latch back, starting from the outside and go up. If all that fails you can use two small screwdrivers one on each side of the tailgate from the inside to pry the latches. None of this will damage your truck except prying the window open. Good luck if you need any more help let me know.
