Fuse or relay problem 2003 Jetta TDI

Before I dig around in my fuse/relay box I would like to know if anyone has this problem.
My cruise control and the "dummy" buzzer when you leave your lights on does not work. I thought these two things may be related to one fuse or relay. Any thoughts?
Thanks!

The dummy buzzer probably has to do with your door switch... does the dome light come on when you open the door? The cruise might be a bad brake light switch, which is probably under recall on your car.
