Hello everyone, I just recently bought a lifted 99 Grand Cherokee, being the fifth Wj I've owned, but the first one with a lift, it's got it's issues but I'm in hopes I can get them squared up... First and for most, the jeep has some body panels replaced by the guy that did the lift and the 4.6 stroker, he also rebuilt the trans, 50k miles ago. Now, the hatch, I don't have a wiper, nothing happens when I hit the switch... I don't have electric window popper... Might have to rip the hatch apart and dig around... Basically, is there anything to be concerned with on the lifted jeep? Never driven a lifted one lol.
