  1. Bulb Check

    Turn ignition off. Remove heated back window indicator bulb from instrument cluster. Ensure continuity exists between bulb terminals. If continuity exists, go to next step. If continuity does not exist, replace bulb.

    Turn ignition off. Disconnect heated back window switch connector. Measure resistance between Black/Yellow wire and Black/Red wire terminals of heated back window switch with switch depressed, then released. If resistance is less than 5 ohms with switch depressed, and greater than 10,000 ohms with switch released, go to next step. If resistances are not as specified, replace heated back window switch.
