The part number for the Jetta passenger side front window regulator is 1J4837462D. Ive heard that they superceeded that number with a new part that is more reliable. Only time will tell. It should run about $120. The 2000 cars have a 2yr/24k miles warranty so it wont be covered anymore.

The regulators suck. Ive been lucky that none of mine have gone bad yet. Watch now that Ive said that all 4 will go bad tomorrow.
