The dashboard lights wont come on, car runs fine but wont shift gears, fuses ok?

What is your question?

I drive a jaguar XK8 1998 convertible. The car is driven often, pretty much every day. There was a hurricane with a lot of rain, and when I got in the car, there was condensation on the inside. The car starts normally but the dashboard lights don't come on, so the car won't shift gears. If I manually make the gears shift I can drive around fine just without a dashboard. Checked all the fuses they are good, and I can make the lights come on so I know they work, its not a problem with the battery either. Any ideas?
