The map, vanity. glove box and trunk lights do not work but the fuse (# 1 10 amp) is good. The map lights do turn on when the door is opened but cannot be turned on when door is closed. All interior fuses located in passenger foot well are intact. Is there another fuse that I should check or something else?

Good morning,

All those functions are controlled by the body control module. The module looks for inputs from the door switches and headlight switch. Once those inputs are found, it will turn on those lights.

You need an advanced scan tool to monitor the module, check for codes set and see if it is getting the proper signals that it needs to do its job.

It is located in the trunk area behind the right side panel by the quarter panel.
