Detailed Description

Standard Ignition DS-789 is a headlight dimmer switch engineered for dependable electrical switching in the Ford Windstar. It combines headlight dimmer control with turn signal operation and windshield wiper/washer functions in one service part, making it a practical replacement when the original switch shows wear, intermittent operation, or loss of function. This DS-789 switch is listed for 1995-1998 Ford Windstar and 1995-1996 Ford Windstar front applications, so fitment should be matched to the vehicle year and position before installation.

Built with copper alloy conductors and tested for both mechanical and electrical performance, this switch is made to deliver consistent signal transfer and switching response. The black plastic housing, rectangular connector shape, and bolt-on attachment method support a straightforward OE-style replacement. This part cross-references Standard Motor Products (e.g., DS-789, SW1087) for the same application.

Common Problems This Part Can Help Solve

• Intermittent or inoperative high beam switching
• Turn signal control failure at the steering column switch
• Windshield wiper delay or speed selection issues
• Washer spray activation problems from a worn combination switch
• Loose, damaged, or electrically inconsistent switch operation

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle position before installation. This DS-789 uses a female rectangular connector with blade terminals and a bolt-on attachment method, so the replacement should be matched to the original switch configuration on the Ford Windstar. Confirm that the vehicle uses the listed front or N/A position application and inspect the steering column wiring and connector cavity condition during service.
