Noticed this weekend that my rear wiper likes to come on by itself. Not continuously, but a single sweep and it is done for several minutes. I haven't been able to find anything that would cause it to happen, such as shifting or turn signal or anything. It is pretty obvious that there is a short in the system somewhere, probably in the wiring on the way back to the wiper motor. I'm looking at the wiring diagram in the service manual (Thanks Ken Gilbert!) but don't know where the wiring runs in the vehicle. If I knew where the wiper module was located I could probably figure it out! Anyone know?

ALSO, I have noticed a puddle of water in the rear passenger floorboard, it appears to be from my condenser drain not being properly hooked up. I have fixed that now, anyone know if the rear wiper problem is related to the water in the floorboards?
