Inspect the connector and socket terminals to be sure they are all making good contact
. lf the terminals are bent, loose. or corroded, repair them as necessary, and recheck the system.
. lf theterminals look OK, check for continuity between them ineach switch position according tothetables lfthere
is no continuity between any of them. check for continuity in the switch harness
- lf there is continuity in the switch harness. replace the combination light switch
