MNJWS Headlight Dimmer Switch for 2003-2006 Chevy/GMC/Cadillac — Direct-Fit Replacement, Controls Headlights & Dash Lights

MNJWS headlight dimmer switch replaces the factory left-panel headlight and dash-dimmer control for many 2003–2007 GM trucks and SUVs, restoring lighting control with a direct-fit replacement.

If the original headlight switch on your Chevy, GMC, Cadillac or Hummer is worn, intermittent, or no longer controlling headlights, panel lights and dome lamps correctly, this MNJWS replacement is engineered to fit and function like the factory unit. Designed to match the form and connector layout of the original, it is compatible with common GM part numbers such as 19381535, 15194803 and ACDelco D1595G, and covers a broad range of models from 2003–2007.

What vehicles will this dimmer switch fit?

This replacement switch fits a wide selection of GM vehicles from the mid-2000s, including pickups, SUVs and luxury models. Check your original part number and connector shape to confirm fitment before ordering.

• Chevrolet Silverado and GMC Sierra (2003–2006, and 2007 Classic models)
• Chevrolet Tahoe, Suburban 1500/2500, Avalanche 1500/2500 (2003–2006)
• GMC Yukon and Cadillac Escalade (2003–2006)
• Hummer H2 (2003–2007)

How does this replacement match the original part?

The MNJWS switch is built to the same physical footprint and connector layout as the OEM part so it installs in the same left-instrument-panel location. While not a genuine GM or ACDelco branded unit, it’s manufactured to meet or exceed key OEM tolerances for fit and function.

• Direct-fit design for original mounting points and electrical connector
• Compatible with GM part numbers 19381535, 15194803 and ACDelco D1595G
• Controls headlights, dash dimmer, dome lamp and door panel lights
• Durable materials and tested electrical contacts for reliable operation

Can I install this dimmer switch myself?

Yes — many owners replace this switch with basic tools and a little patience. The unit mounts on the left side of the instrument panel and typically requires removing a trim panel, unplugging the electrical connector, and swapping the switch in place.

• Simple hand tools usually sufficient; no special equipment required
• Unplug battery if you prefer extra safety before working on electrical parts
• Follow vehicle trim removal steps to avoid breaking clips or bezels
• Reconnect harness and test all lighting functions before reassembly
