I would suggest inspecting the hi/ low floor switch and the wiring to it first. It is fairly easy to access and a common problem area due to moisture. Then the light switch can be checked. First check for 12v between the switch and ground. If you don't have a wiring diagram just do a search above. And this link should help.

Good luck.
