I'll even come back and add this. Even if you do find a "good" switch, do this experiment. Cut the headlights on bright. Leave them on for about 15 minutes and reach under the dash and grab the headlight switch. But be careful. It's gonna be HOT. That's because they were never really designed to carry that load. Chrysler should have run the load through relays. To me, that right there is enough to upgrade. Just food for thought.
