1995 Ford Explorer WINDOW

Electrical problem
1995 Ford Explorer Four Wheel Drive Automatic 187000 miles

About 3 weeks ago my driver window stopped working, replaced the motor and all was well. Then it just stopped again, in the rain conveniently, and the same thing all over again, no sound from new window motor, only clicking under steering column. Also, same driver door handle stopped working and gets stuck in the open position, door ajar light keeps coming on randomly, sometimes overnight, and drains my battery. Also, power mirrors are not working either, same door, and its not the fuse. What should I be checking and how should I go about fixing this? Any help on this is so greatly appreciated.
