I have a 2000 dodge grand caravan. I have no Dash lights, no Tail lights, and no front marker lights. I do have blinkers, head lights, and break lights. Have checked the fuses and they are in working order. Could it be the switch that is the problem or is there some where else to look first?

Check or replace the ignition switch for wear, pitting, or melting.

How do you check the ignition switch?
