Detailed Description
Standard Ignition DS-970 is engineered as a replacement headlight dimmer switch for vehicles that rely on a multifunction steering column switch. The unit uses copper alloy conductors for strong electrical conductivity and reduced resistive loss, while the switch assembly is 100% tested for mechanical and electrical switching performance. For Ford Ranger and Ford Explorer service, as well as Ford Bronco II and Mazda B3000 or Mazda B4000 applications, DS-970 restores control of lighting, turn signals, washer spray, and intermittent wiper operation through one integrated component.
This part cross-references Dorman - HELP 2330830 for the same application.
What It Is Used For
- Restoring headlight dimmer operation when high/low beam switching becomes inconsistent
- Correcting turn signal control issues at the steering column
- Repairing intermittent windshield wiper delay or speed selection problems
- Addressing washer spray switch faults from worn internal contacts
- Replacing a worn multifunction switch on Ford Ranger, Ford Explorer, or Mazda B3000/B4000 vehicles
Installation Notes and Tips
Compatible With 1990-1994 Ford Ranger, 1991-1994 Ford Explorer, 1990 Ford Bronco II, 1994 Mazda B3000, and 1994 Mazda B4000. Also fits 1989-1994 Ford Ranger and 1992-1994 Ford Explorer with intermittent wipers. Verify connector shape, terminal count, and switch functions against the original part before installation. Because this is a bolt-on electrical switch, careful alignment of the steering column controls and connectors is important for proper operation.
Quality Assurance
Standard Ignition builds this switch with robust materials and copper alloy conductors, then tests each unit for mechanical and electrical switching performance. DS-970 reflects the brand’s long-running focus on technician-oriented electrical service parts.
