Make sure you get the all fluids and filters changed asap. Especially since you mention the transmission "doesn't shift badly"

After checking the fuses for the windows, establish if it is the wiring or the motor that is dead. Pull the panels off and apply a 12V battery to the terminal attached to the door to see if the motor moves. If it does, wiring is frayed in the door, if not, motor replacement!
