Checking the cable

HINT: The fault could also have been caused by the windshield wipers sticking. 

Check the cable between central electronic module (CEM) terminal #16B and motor (6/1) terminal #3. Check for a short-circuit to supply voltage. See Short-circuit to supply voltage. Permanent faults . Check for an open-circuit. See Open-circuit, permanent faults .

Check the connector.

If no other faults are found try a new windshield wiper motor (6/1).

Remedy as necessary.
