Pinpoint Test C12 - Check Headlight Lift Switch
With ignition off, disconnect and remove headlight lift switch. With headlight lift switch on, measure resistance between White/Green wire terminal and White wire terminal at headlight lift switch. If resistance is less than 5 ohms, go to test C13. If resistance is more than 5 ohms, replace headlight lift switch. With headlight lift switch off, measure resistance between White/Green wire terminal and White wire terminal at headlight lift switch. If resistance is more than 10,000 ohms, go to test C13. If resistance is less than 10,000 ohms, replace headlight lift switch.
