When the ignition switch is in the drive position, current will flow:
*from fuse 5, via 29-pole red connector 152B, to switch 61 for the headlamp wipers and washer, and
* from fuse 8 to each headlamp motor.
When the stalk switch is moved towards the steering wheel rim, contacts "A" will close. Both motors then start simultaneously.
When the stalk is released and the circuit is opened, the wiper motors will still be energised(across fuse 8). When the wiper motors have completed five strokes, the limit switches incorporated into the motors will open the circuit and the wipers will stop in the parked position.
A diode in each motor prevents the current from the feedback circuit of the motor from flowing back to the washer motor.
Each wiper motor incorporates overload protection with a protective switch which is actuated by a resistor. The switch is in series with the motor and will trip if the load should exceed a predetermined value.
It sounds like you got a problem inside the motors, maybe the internal limit switches.
