PINPOINT TEST D: THE INTERMITTENT WIPER SPEED DOES NOT OPERATE CORRECTLY

Normal Operation
Under normal operation, the windshield wiper motor receives open and ground inputs from the multi-function switch through circuits CRW17 (GN/VT), CRW18 (VT/WH), CRW19 (BU/OG) and CRW08 (VT/OG) to activate the wipers to the appropriate modes. Mode of operation is dependent on the signal(s) received from the multi-function switch.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Windshield wiper motor
