Service Procedure
The following procedure describes how to inspect and replace the hazard warning flasher switch, OR inspect and replace the multifunction (turn signal, headlamp dimmer, and windshield wiper/washer) switch assembly. The part that you replace will be determined during the inspection portion of this procedure. Do NOT replace any parts until after performing the inspection procedure.Inspection Procedure
1. From inside the vehicle, depress the hazard warning flasher switch located on the top of the steering column.
2. Depress the hazard warning flasher switch again.
^ If the hazard warning flasher switch did not stick in either the up or down position, proceed to the section titled "Replacing the Hazard Warning Flasher Switch." Do not order any replacement parts until instructed to in the additional inspection procedure included in that section.
^ If the hazard warning flasher switch is sticking in either the up or down position, replace the multifunction switch. Proceed to the section titled "Replacing the Multifunction Switch."
Replacing the Hazard Warning Flasher Switch
This procedure describes how to replace ONLY the hazard warning flasher switch assembly. The procedure includes information on how to remove the original switch, where to apply the lubricant on the new switch, and how to install the new switch.
DO NOT use this procedure if the inspection above indicates that the multifunction switch requires replacement. Contained in this procedure are unique steps to address features or options such as cruise control, standard or tilt column, and a column mounted automatic transmission lever.
