The windshield wiper motor module is part of the windshield wiper motor cover and controls wiper motor operation. The accessory voltage supply circuit to the windshield wiper motor assembly is used to operate the wiper motor in all modes. The windshield wiper motor is a 2 speed motor and is operated at low speed in all modes except HIGH. The accessory voltage supply circuit to the windshield wiper/washer switch is used to supply the windshield wiper switch signal circuits. The windshield wiper switch signal circuit voltage levels to the wiper motor module determine the wiper motor operating mode.
When the wiper/washer switch is in the LOW position voltage is supplied through a 24K ohm resistor within the switch to the windshield wiper switch signal 2 circuit, and accessory voltage is supplied to the windshield wiper switch signal 1 circuit. The reduced voltage from the wiper switch signal 2 circuit and accessory voltage from the wiper switch signal 1 circuit causes the wiper motor module to close the wiper motor accessory voltage supply circuit to the wiper motor low speed terminal.
Windshield wiper/washer system MIST operation is identical to LOW operation except that the MIST switch is a press and release type. When the wiper switch is moved to the MIST position and released, low speed wiper motor operation is started and will continue until 1 cycle is complete. If the wiper switch is moved to the MIST position and held, the windshield wiper motor will operate in the LOW mode until the switch is released.
GM Part No 22711472
Windshield wiper motor park operation is controlled by the wiper motor module using an input from the park switch within the wiper motor assembly. When the windshield wiper/washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position.

Could be anything but based on experience the probability points to the self cancelling switching in the motor gearbox.

Yes the solution is to replace the wiper motor, the auto park circuit is defective.

check first the fuse.
the fuse box might be located just above the left foot pedal under the steering wheel!

The wiper relay is located behind the center of the dash i am sending you a picture of whe
SOURCE: Wipers stop in the middle of windshield when turned off
check to make sure the wipers are at its right angle on the vehicle, loose the nuts and place both wipers close to the bottom of the wind screen
SOURCE: put in a new wiper motor 1997 e39 528i bmw\it stops in the middle
Remove arm(s), put wiper motor in park,(shut off) then re-install arm at base of windshield where they were before,when shut off.(in park position.)
