Was at the dealer yesterday. They gave me bad news.
"The wire harness rusted out under passenger seat"
It is causing high resistance. They checked for power at the wiper motor
and backtracked through tha circuit. Found the source of the resistance all "owing
only 4V to get to the wiper motor" It need 12 V, they tell me.
They claim that most of the problem am having is connected to the wire harness rustiness.
9000 dollars to change. Sad.
When I bought the car there was water in the passenger area. This supposedly is the cause.
They actually told me the car will eventually refuse to start one day.
I wonder if anyone has a cheaper idea of fixing this.
