MCC/Smart Headlight Switch Replacement
If you're out at night and jump in the car to go home and the lights don’t go on in your MCC/Smart, what to do? Getting home becomes rather tricky without lights and, unfortunately, your MCC/Smart will need to be parked up until daylight. At that point, an auto electrician will need to check over the wiring, fuses, relays and connections, and one possible conclusion is that the headlight switch has failed.
The headlight switch can eventually fail. The switch can also be damaged and get knocked about, especially if it is on the steering column and used for other functions.
Most headlight switches are of plastic construction. A dash switch is usually a round dial or toggle switch while a steering column switch is a multi-function stick that protrudes from the column. Both have electrical connectors at the back or base of the unit which connects to the lighting relay and wiring circuit in your MCC/Smart. When you select the headlight function the relay opens or closes the circuit to activate that function.
Electrical components are best replaced or repaired by an auto electrician. This will ensure wires are connected correctly and there is no chance of an electrical malfunction on your MCC/Smart.
