Mechanical Multifunction Switch Diagnosis

Switch, Multi-Function

The multi-function switch is a combination turn signal, hazard and dimmer switch which has a number of on/off switches packaged as a single unit. Testing for electrical malfunctions can be accomplished with a continuity tester. Malfunctions can be determined by checking continuity between the feed and function terminals of the switch.

Prior to testing, make sure hazard knob is pushed in fully to the OFF position. If the suspect circuit is satisfactory, the concern is elsewhere in the system.






Refer to the diagnostic charts and the illustration to resolve concerns with the multi-function switch.
