I checked the wiper pump motor and it checked out ok, and the fuse still blows. It is strange...the fuse blows on the first click of the key.
Fuse F44 is a hot in accessory (ignition key position 1), run and start line.
It goes to the telephone connector X400 in the center console area, rear wiper unit, washer pump, wiper washer module behind the glove box and the wiper switch on the steering wheel column.
The splice X10022 where it alls comes together is shown to be in the fuse box. The splice is a taped crimped connector.
You could start unplugging things like the wiper switch, radio and wiper washer module.
The line going to the rear lid is a 3 pin connector that I doubt would short from being disconnected unless it got pinched. The two pin hot at all times line is more likely to if not insulated.
