bad wiring connections, bad switches, and the most expensive bad window motors. i've already had to replace a motor in my 99 and a switch has gone bad too good luck.

I'm pretty sure your problem is in the drivers door wiring bellows( the rubber boot between the door & the body) I see lots of these, pull back the boot,& I'll bet you find a broken wire in there There is a drivers,& passengers door module & this wire if broken will take out the passenger front,& both rear doors,Fix it & you should be fine.
