You have a voltmeter?

Actually my mechanic was doing this troubleshooting this and he has one. I did notice that he was not getting any voltage from the dome ligts.
Expert:  Toyota Service replied 1 year ago.

You either have a loose fit to the dome fuse in the fuse panel under the hood, the short pin (right next to the dome light fuse) is loose or missing, or the fuse is actually blown. if he is applying power to the Positive terminal, he is backfeeding power into the system. This indicates that there is not power in the system, and the circuit is good. The problem here is lack of power, most likely in the fuse panel under the hood.
