Detailed Description

Standard Ignition DS-667 is a headlight dimmer switch engineered for service replacement on Chevrolet Cavalier applications from 1991 through 1994. It is designed for vehicles without cruise control and serves as a combo switch assembly, handling headlight operation, high-beam switching, and turn signal control from a single unit. Copper alloy conductors are used to support strong electrical conductivity with low resistive loss, and each switch is tested for mechanical and electrical performance before release. The DS-667 part number is also referenced in interchange listings for service matching, including DS-667 for the same application.

Common Problems This Part Can Address

• Headlights that do not switch properly between low and high beam
• Intermittent or failed dimmer switch operation
• Turn signal control issues at the steering column switch
• Worn or damaged combo switch contacts
• Electrical switching faults caused by aging internal components

Installation Notes and Tips

Verify that the vehicle is a 1991-1994 Chevrolet Cavalier without cruise control before installation. This DS-667 switch uses a bolt-on attachment method, a single female rectangular connector, and blade terminals, so connector shape and terminal count should be matched to the original unit before removal. Confirm indicator markings and switch functions align with the existing column controls prior to final assembly.

Quality Assurance

Standard Ignition builds this switch with robust materials and copper alloy conductors, then tests each unit for both mechanical action and electrical switching performance. The DS-667 is a new replacement part intended to meet service-professional demands for consistent headlight control.
