I have a 4 door, 2001 blazer,with a tailgate and lift glass, there is a button on the dash and a black push button on the tailgate itself to pop the glass. First problem is my glass would pop open at any time, like even going down the road a few times. So i started locking the truck and taking off, that worked, until you stopped and unlocked the doors then again it would pop the glass as you unlock the door almost instantly. Its cold here so i left it at that for know and gets dark so early too. Now this morning I went out and it won't open at all, I don't hear nothing when I press either button too. I have read a lot of posts on here about not opening the glass but they normally state they here the actuator, in my case you hear nothing at all. I am sorta lost on what to do, sorta seems electrical problem, but i dont know, thanks for all your help if you can.

 

Since you have already posted about this problem, there is no need for a second thread. Anybody wishing to reply can do so at your original thread.
