Two problems related to power window have been reported for the 1997 Plymouth Grand Voyager. The most recently reported issues are listed below.
Air conditioning system: evaporator was replaced 3 times so far, first time being under 3 year warranty. Service engine light stays on all the time now, even after being diagnosed with "no problems" and being reset. Lately, the windows won't go up and down until the car is stopped and restarted. Same thing with the speedometer and the tachometer. They just "go dead".
Started when I would take off in first gear, it would vibrate really hard, like a manual transmition does when it needs to down shift. Then I was almost in a collision, when I was stopped on the side of a hill, and went to pull over, and to my surprise I rolled backwards, as if in nutral. My trasmission was gone. After a very large tow bill, and 1500 rebuilt transmission, my dim lights only work when they want to, the passenger window is to the point where it almost wont go up. . . . . There's almost too much more to go on.
