Sounds like a switch gone bad. DOnt know if its an assemby, but its worth a search here on the site. On my 93 the switches are individual, but under a cover plate and I think the same for the wifes 95. Id have to check my dads 02 to see. If you can get to the switches and they are individuals, just change your drivers side for the passenger side window switch and see if that solves it. If so, then it is a switch.
