Title: Voltage drop
Post by: VileZambonie on March 04, 2007, 08:25:00 pm

Well then it's one of two things

1)Mechanical resistance

2)electrical resistance

If the winshield is wet do they work normal?

Do you have a volt meter? You can do a simple voltage drop test before the motor, at the motor and or after the motor.

Essentially you should drop all source voltage at the motor. There should be no voltage drops before or after which would indicate resistance and give you that slow motor.

Try lubing the wiper transmision assembly.
