Iam dealing with the same issue... Have you wheeled your rig? Does your windshield leak on the D.side? only way to find out is look for rust behind your dash... As said before, you most likely have a short.. I currently have no dash lights and my head light switch dims my running lights... Ya, I have water issues and shorts all over the place... Its a wheeler for the most part...

Hope you figure it out...

oh and The punisher bezel stickers look SICK!!
