SOURCE: passenger side window

it could be a bad swich on the passenger side because they comunicate each other, or sometiems the wiring brake just by the door where all the wiring goes to the boddy you need to open the black hose with a nife and look for broken wiring circuits

Replace the Driver side window switch. These have a corrosion issue.

I've had a similar problem with my 2003 Buick Century. In my case, the driver's side front window one day went up and would not come down. I knew that the switch was malfunctioning by sticking in the up position since the window continued up despite the fact that Iet off the switch when the window was half way up and it continued going up. I had to pull over and pull the master switch assembly from the door panel and unplug it to prevent the window motor from being damaged by the constant power feeding it after the window was up. Basically, it would have burned the motor out. I cleaned the switch and it now works fine most of the time. I still need to replace the assembly. Not sure this is the reason in your case. I would check the back window and see if it goes down with the switch on the back door panel. If it does, then you are having problem with the master switch assembly on your front door panel. Moisture from rain from the window being down during rain or dirt may have corroded the switches' contacts.
