All of a sudden my fog lights stopped working. The bulbs are good and they are the correct watts. I haven’t had any work done to my car. All of my interior and exterior lights work as they should. When I turn on the multi switch for my fog lights the fog light symbol doesn’t illuminate on the dash. What can I check or do to narrow this down. Could it be the multi switch? If so, how can I check this switch before replacing it? I ran 2 jumper wires to both fog lights individually to the battery to test them and they worked that way but they won’t work once I connected the wire harness back to them. Any help is appreciated because a few auto shops can’t figure this out either.
