Both headlights are not working in 2002 Safari Van

Check both headlight bulbs, check for power and ground (the ground wire is black). If no power either wire to ground remove the headlight switch in the dash. The bezel around the cluster just pulls away. Check the connector to the switch. The large red wire (power) or the black (ground) may be burnt. Repair if possible or replace if melted. There isn't a headlight fuse. If only one setting works (eg. hi beam only both sides, no lo beam) then the dimmer switch is at fault. Its part of the turn signal switch.
