I assumed you already checked your fuses, bulbs and that they do not work even when the doors our open.
Get to the root:
First open the door and remove the light assembly. Then use a lighted probe to check for power in the wiring harness at the light assembly connector.
If your connection is hot (has power) then replace the light assembly.
If you don't have power at the connector then remove the door contact switch and bridge the two wires together with a jumper wire and check the wiring harness light assembly connector again to see if it is hot.
If it is hot then replace the door contact switch.
If not then look for the short (no blown fuses probably no short). :mrgreen:
