I am having a problem with my window and I think I know what I need to do but I wanted to check to see if there are any other tricks before I spend any cash. When I roll my window it continues to want to roll up and makes a clicking noise because it reached its max. I am thinking I need to get a new window regulator or the window is off track. Any suggestions.

My second problem is that all my doors lock but the driverside door, when I have the door open and hit the lock button it makes the looking noise but does not lock. The lock tab on the door wants to move but it seems like it is stuck.

I have a 2000 Jeep Cherokee Sport 4.0 4WD
