Wiper Switch: Description and Operation

Multi-Function Switch:

SYSTEM OPERATION
The windshield wiper and washer switches are contained in the multi-function switch assembly. The multi-function switch assembly is secured to the left side of the steering column. A knob on the end of the multi-function switch stalk is rotated to select the desired wiper speed or intermittent wipe delay, or depressed toward the steering column to activate the washer system.

The multi-function switch contains circuitry for the following functions:
- Turn signals
- Hazard warning
- Headlamp beam selection A
- Headlamp optical horn
- Windshield wipers
- Windshield washers.

However, the multi-function switch cannot be repaired. If any function of the multi-function switch is faulty, or if the switch is damaged, the entire switch assembly must be replaced.
