On 1981---83 models, place slide switch in on position.
1. Disconnect switch electrical connector from main harness connector at base of steering column.
2. Connect ohmmeter between terminals 1 and 2 on switch connector, Fig. 10. With engage button released, meter should indicate continuity; with button fully depressed meter should indicate infinite resistance.
3. Connect ohmmeter between terminals 1 and 3 on switch connector. Meter should indicate infinite resistance.
4. Fully depress engage button, then release button halfway to engage position. Meter should indicate continuity.
5. On 1981---82 models, release engage button and move slide switch to resume position. Meter should indicate continuity between terminals 1 and 3.
6. Return slide switch to on position on 1981---82 models, then on all models, connect ohmmeter between terminals 2 and 3 on switch connector.
7. With engage button released, meter should indicate infinite resistance. With engage button in halfway (engage) position, meter should indicate continuity between terminals 2 and 3.
8. If switch fails to perform as outlined, switch assembly is defective.
