Detailed Product Overview

The Standard Ignition CBS-1420 headlight dimmer switch is engineered with copper alloy conductors for strong electrical conductivity and reduced resistance. It is 100% tested for mechanical and electrical switching performance, helping ensure consistent operation of the lighting and wiper controls in your Lincoln Navigator or Lincoln Aviator. This part number, CBS-1420, is a practical choice when the original combination switch has worn contacts, intermittent beam selection, or failed stalk functions.

This part cross-references Standard Motor Products (e.g., SW3930, SW6131) for the same application.

Common Problems This Part Can Address

• Headlights that will not switch between low and high beam
• Intermittent or inoperative turn signal operation
• Windshield wiper delay or speed control failure
• Washer spray function not responding at the stalk
• Rear wiper or rear washer control issues

Installation Notes and Tips

Install CBS-1420 as a bolt-on replacement using the existing 3-cavity connector layout and 23 blade terminals. Verify connector shape, terminal count, and vehicle year before installation. Because this switch controls multiple functions, confirm proper operation of the headlights, turn signals, windshield wipers, washer spray, and rear wiper controls after installation on the Lincoln Navigator or Lincoln Aviator.

Quality Assurance

Standard Ignition builds this switch with robust materials and tests each unit for both mechanical action and electrical switching performance. That validation helps support reliable service in daily-use lighting and body control applications.
