hey guys. strange problem- my passenger window (front) stopped working. it will go up and down very slowly and sometimes- not move at all. at first i thought it was bad wiring- or a tired window motor - but then i noticed that if i shut off the engine and re start- it works fine- up and down without a problem. on other occasions it will not work after the kj has been parked for a day or two- maybe...maybe...it will go up and down about an inch, and very slowly....- but after 5 minutes it works fine. any ideas?
