Product Overview
Headlights that will not switch between high and low beam, flicker when the control is moved, or fail in one switch position can point to worn contacts after bulbs, fuses, relays, wiring, and grounds are checked.
This dash control must match the original connector, knob functions, lighting options, and trim configuration. Compare 19381535 and the rear terminal layout before purchase.
