Liftgate will not open

I cannot get the liftgate open. How do I get into the lift gate to fix the problem. I do not see any interior panel screws to get at the door mechanism. Does the plastic interior panel just pry off or are their some hidden screws? Is there a saftey latch somewhere in the interior to get the door open to fix the problem... I am at a loss to get at the latch.....

The panel prys off. What year 97+?

Re: 2000 xj rear hatch wont open please help!!!
pull the handle and while it's pulled, smack to the left and right of it and it should pop open for you. All that's wrong.....if its the latch.....is that it is probably out of adjustment or worn. Smacking next to the latch has always worked for me.....yeah, its a 97+ problem too.

Yep, my 2000 had the same problem. Just yank it to the left and right while pulling on the latch and it should open.

i have the same prob on my 98. for a while it worked if i pushed on the bottom of the hatch while pulling the handle. now mine wont open at all, so im gonna have to try hitting it!

2000 Sport I just want to get the liftgate open so I can see and fix the problem.
