Wiper motor won’t shut off?
Problem is located in the parking switch. Located in circle in pic. When you switch wiper to OFF, power is transferred to the blue wire soldered to this switch. Motor keeps running until plastic cam inside this switch is pushed by raised part of motors pinion gear. This pushes on the plastic cam to open the parking switch. At this point, the motor shuts off hopefully in the parked position. Pic shown is a 67 Vspeed, however they are all similar in design and operation.
