The courtesy lights don't have a relay.
The circuit is energized continuously and the door switches provide the ground.
Check to see that the plug in the
C100 C200 is plugged in (orange wire and white wire on some plug)
The C200 is located above the fuse box at the base of the driver side A pillar. The easy way to access time C200 is to pull the driver side speaker out of the dash.
If above is all OK, change the bulbs and check the BAT and CTSY/LID fuses.
Edited to correct errors.
