Hello, there are three types of courtesy lamp circuits, new style- base, new style- up level, old style.

I don't know which you have? I looked at, new style base. There is a courtesy lamp fuse in the underhood fuse box, you not only check the fuse, check that the circuit has voltage.

When you open the door, there should be a switch that grounds a circuit. The bcm sees this and grounds the inadvertent power relay and that relay supplies voltage to the courtesy lamp relay, which the bcm also grounds.

Can you maunally turn on the dome lamp/s, maybe the bulb is bad?

The bulbs are still good if I press the buttons for the front courtesy lamps they come on but it's just when I open the doors they don't come on, the lights stopped working after I installed a K& N cool air intake i'm assuming when I disconected the battery and then reconected it I screwed something up electricly
