Re: 156 Windscreen Wiper Problems
As Hoygaard says there is a problem with the Magnetti Morrelli motors fitted to 156, 145 and 146. The fact they only work on high speed and will not park means there is probably a problem with the parking plate fitted to the gear in the motor.
It's no longer making contact between the flexible fingers in the gearbox housing and the circular park plate. Grease is contaminated or the flexible fingers are worn. On high speed there is no connection through the park plate, so it will still work but not park. Worth looking at the inside of the motors housing first, probably.
If you do a search for wiper motor, grease, on 145 and 156 sections on the forum you will find a lot more posts and how to fix it.
