Detailed Description

Standard Ignition CBS2442 is a headlight dimmer switch designed for vehicles that use a combination switch to manage exterior lighting and turn signal operation. It is built to restore proper control of the headlight dimmer function, including high beam selection, fog light operation, running lights, and turn signal signaling where equipped. This part cross-references OE numbers such as 23388770 and 84117379 for the same application.

Compatible With 2017-2022 GMC Acadia with fog lights and automatic high beam, 2023 GMC Acadia, 2022-2023 GMC Terrain, 2020 Buick Enclave, and 2020 Chevrolet Traverse. The CBS2442 part number is also a useful reference when verifying the correct replacement for these applications.

Common Problems This Part Can Address

• Headlights not switching correctly between low and high beam
• Fog light control not responding as expected
• Turn signal or directional indicator operation loss
• Intermittent or failed combination switch functions
• Dimmer switch electrical faults caused by worn internal contacts

Installation Notes and Tips

Verify connector shape, terminal count, and switch functions before installation. This switch uses a clip attachment and a single female rectangular connector, so matching the original connector and dash switch layout is important. Confirm vehicle-specific fitment for GMC Acadia, GMC Terrain, Buick Enclave, or Chevrolet Traverse before replacement. The CBS2442 is intended for direct replacement of the original combination switch assembly.

Quality Assurance

Standard Ignition builds this switch with robust materials and copper alloy conductors, then tests each unit for mechanical and electrical switching performance. That process supports consistent operation in service applications and helps ensure the replacement meets the demands of daily use.
