I have a 99 4dr blazer and i have a problem getin the back window to close sometimes, It will look closed but then it pops open like its not catching. Anyone know how i can fix it or what the problem is?

 

check the latch. after 11 years, it may need a bit of love (read as 4wd 40) to get it grabbing and releasing like it should. if that checks out, you may want to check the hinges to make sure they are still solid. if they wiggle a bit as the lift glass comes down, it may not line up right. last thing, take a peak at the dash control (if you have one) and clean the connections there to ensure it's not auto-popping your glass. :icon_shrugg:

see if you can pin point a source for why it is not staying shut...

 

Ive put some 3 and 1 oil on it and it kinda helps but after like an hour it still dose it. I dont know and poper inside I just have a button on the outside.
