Lights will not come on when door is opened?

Check in the under the hood fuse box. Fuse 16 and Fuse 18 TBC fuses 2 and 3. SHould be a 15 amp blue fuse. These come from the body control module.

If it does not come on with any doors open. It also my be the dome switch cut off or bad. If it is just one door, it's probably the switch in the door, may be stuck or bad.
