I had similar issue, my drivers side quit working but i had got it wet when i was washing the car. I tried drying it out with a hair dryer and compressed air to no luck. so i took the door seal out and put it in the house for a few days and tried it again, and wala it worked again. I also unplugged the passengers door seal plate while i had the drivers out so that the transformer wouldn't over voltage the one that was working, because they both come on when you open ether door.
