Windows, locks and interior lights not working!!!
 

I have a 99.5 A4 B5. My power windows, power door locks, and interior lights stopped working. None of the fuses have blow (I have checked them about 20 times). There was water on the floor of the drivers side(which is now dried and it still isn't working) and I also replaced the central door lock pump in the trunk of the car to see if that was the problem but no luck. Is it possible that its the relay that has gone bad? If so where is it(and please be as specific as possible)?
Also, could it be the module that has gone bad? If so where is it located? I'd appreciate any kind of help because it's driving me crazy.
