Which fuse is for the button that the dome light comes on when door is open?

Hi,

The fuse for the interior courtesy lamps is in the instrument panel fuse box. It will be fuse 3 in the box. If you look at the last two pics below, I highlighted the fuse and highlighted everything it powers.

I attached the wiring schematic for the circuit as well so that you have a reference.,

If you check the fuse and it appears good, confirm it has power to and from it.

Let me know if this helps or if you have other questions.

Take care,

Joe
