I can't get my hatch in the back of my truck to open it won't open any more. What can I do.

After a while, the mechanism (actuator) that unlocks and releases the rear glass hatch in your Blazer will eventually burn out. when it does, there is really no way to open the glass and lower the tailgate.
The only way to replace the burnt out actuator is to open the tailgate which you can't because the actuator is burnt out.

I've read stories that even the dealers don't know what to do, some have even cut up the back panel to reach the so-called manual release. Others said they pulled back the glued on carpet to search for it also.

Well if you don't want to hack up the tailgate panel or rip out your carpet, here's the easy way to open the glass:

You just pull back the interior tailgate panel right above the bump in the middle where the latch is. There are no screws or bolts in that area, you can safely pull it back about 2 inches. Then you'll have to stuck your finger in and push down the release bar.

When you get your finger back there, you should be able to feel for the part that need to be pushed down. When that part is pushed down, the glass has been unlocked.

Good luck and hope this helps, The actuator that needs to be replaced costs $58 from the dealer. Keep me posted be glad to help you with this problem and don't forget to rate.
