Rear Defogger Switch

Ensure rear defogger switch is in OFF position. Disconnect rear defogger switch harness connector C380. See Figure. Using an ohmmeter, measure resistance between switch terminals No. 3 and 12. If continuity exists, replace rear defogger switch. If continuity does not exist, continue test. Turn rear defogger switch to ON position. Measure resistance between switch terminals No. 3 and 12. If continuity does not exist, replace rear defogger switch.
