i have a 2000 lincoln navigator. about a month ago my window on the driver side door came off the hinges so it wouldnt go up, and i had no idea it was going to rain that night and the next morning when i looked out i freaked out and found everything on the driver side wet, from the whole seat to the dash and controls and everthing so when i was about to leave i decided to turn on my wipers and only the passenger one worked. the driver one only moved about 3 inches then started moving faster without stopping and it even start going off the windshield and hittin the rearview mirror, any idea how to fix this ? thank you, i need to fix it soon to sell it already.
