Take back control of your lighting and signaling with the Standard Ignition Hazard Warning / Headlight / Turn Signal Switch (CBS-1186), a direct-fit replacement for the 1999-2004 Jeep Grand Cherokee. This multifunction combination switch bundles the headlight, turn-signal, and hazard-warning circuits into a single steering-column unit, so one part addresses several driver controls at once.
- Three functions, one switch: operates the headlights, the left/right turn signals, and the four-way hazard flashers from the column.
- Direct-fit design: made to install in place of the original switch on the listed Grand Cherokee applications.
- Replaces a failed original: swaps in for a worn-out switch so the affected lighting and signaling circuits can work as intended.
Signs the original switch may need replacing include turn signals that won't activate or cancel, hazard flashers that stay dark, headlights that flicker or won't switch on, or intermittent operation as you move the lever or knob. Because these symptoms can have other causes, diagnose the circuit before ordering; if the switch is the fault, this replaces it.
