Headlight problem during rain

Recently my headlights have started going on and off while driving in the rain. They work properly when I am stopped or when it is not raining. How do I begin to find the problem when they are working when I am checking them out? Where do I start when there are no obvious loose wires or connections?
I would welcome any suggestions.
Rufus

The switch is heating up and protecting itself like it was designed. For some reason only in the rain though.

You can replace the switch easy enough and or do the headlight relay mod.

It's the switch itself. You can pull it out and try and clean it or replace it.

Here's a thread that discusses that and new replacement switches: http://www.jeepforum.com/forum/f12/h...eaning-865127/

If you own a YJ, you need to own a multimeter. Exactly for things like this. Is more than likely your switch, but if there's a short somewhere causing the whole problem, you'll need a meter to chase it down. Even the really nice models aren't too expensive, I recommend picking one up, it'll pay for itself in saved headaches in no time. Good luck!

Thanks for the info and link. I think I will replace the light switch. Cheap enough fix if it is the source of problem. I have a multimeter but since the problem only occurs when running on road in rain it is hard to use the meter to check problem.
I will be happy to spend the money for a new switch on the chance it will work.
Thanks again,
Rufe
