I have a 1995 blazer 2dr.. there is a button on the key remote and in the blazer next to where you turn the headlights on. there is also a button the the rear of the blazer right under this glass.... well sometimes i can use alll these button and the glass still will not "pop" open. this morning i had to put my baseball bag in the rear and it took me 5 minutes to get that glass to come open.. i kept using all the buttons. it just makes a little noise like its tryin to unlatch the glass but it still dont come open...anyone have any sugestions?

 

Does it just randomly decide to work or is it completely inoperative?

If it makes noise, but never pops, then you likely have a broken actuator arm in the back. There are several ways to go about fixing this, but you will either drill holes or brake things in every one of the methods of opening it.

Run a search for "rear hatch" or something to that effect.
