Normal Operation
On Freestyle vehicles, the washer pump motor is grounded to the chassis by internal relays in the windshield and rear window wiper motors through circuit 946 (VT/LG) when the windshield washer is activated, or through circuit 941 (BK/WH) when the rear window washer is activated. On Five Hundred and Montego vehicles, the washer pump motor is grounded to the chassis through circuit 1205 (BK). When the wiper switch is pressed to the windshield wash position, a ground signal is provided to the windshield wiper motor and module assembly on circuit 28 (BK/PK) and the internal module activates the internal washer relay, which provides power to the washer pump motor through circuit 941 (BK/WH). On Freestyle vehicles, when the rear washer is activated, the internal relay in the rear wiper motor provides power to the washer pump through circuit 946 (VT/LG).

Possible Causes
- Open in circuits 28 (BK/PK), 941 (BK/WH) or 1205 (BK)
- Inoperative wiper switch
- Inoperative washer pump motor
- Inoperative windshield wiper motor
- Inoperative rear window wiper motor (Freestyle only)
