my 98 xj with 190k has an electrical problem... somewhere between the main conrtol switch for the windows and the passenger rear window.. anyone else have any problems like this? it will roll down but not up..? i also seem to get a small shock every time i get out... one other thing ive noticed too is that my volt gage will bury in the 19 area from time to time for no reason.. my mechanic said its because of my optima battery and that it wont hurt anything.. any thoughts? Please!!!!
