Ok, in my mom's '95 Jeep Grand Cherokee Laeredo 4x4 it was having some surging problems at freeway speeds at the begining of the winter...... so she would just drive it around town and when she needed to go somewhere on the freeway, my dad would take her. Well, she let it sit for a few weeks, and now, the car won't move... whether I put it in gear or not, it will just sit there... the engine runs fine, but nothing... I can put the car in nutreul and also disengage the 4x4 and it sits.... I checked the breaks and they are stuck...... so I'm kinda at a loss on what the heck it could be....... the Tranny isn't shot either, cause I can feel it shift when I shift it into each gear. Any thoughts?
