High Or Low Beams Inoperative
- Disconnect 6-pin and 14-pin connectors at combination switch. Measure resistance between terminals with the switch in the listed positions. See COMBINATION SWITCH RESISTANCE table under HEADLIGHTS INOPERATIVE test. Go to next step.
- If combination switch is okay, but high beams do not work, repair open in Red/White wire between headlights and switch. If switch is okay, but low beams do not work, repair open in Red/Black wire between headlights and switch. If combination switch is not okay, replace combination switch.
