The passenger window has consistently been a problem since I bought the car. I've had the window motor and switch replaced both under the original manufacturers warranty AND under my extended warranty! And now, sometimes it will still go up so slow that I think it will stop, and it will only roll up by the passenger door switch. The driver door switch will not roll the window up, but will make it go down. And that switch has been replaced as well. I've met other Magnum owners that have had the same problem repeatedly.
