i changed strean and fluid,but no difference

2002 Mercedes-Benz S430
Question: passenger side mirror/seat control not functioning and window will not operate.

Also do you have to replace both sensors at the same time thats on both sides

I ahve a GPS/radio combo with the cassette behind and an Alpine disc changer in the trunk. My GPS functions with no problem but my radio will not come on. This happened before and I unplugged the changer, pulled the fuses to check them, powered off the dvd navigation player. And eventually the radio worked again. I believe that it was a fluke that started working. Where should I look next?

Do you think it is a fuse, the switch, or a defective control on the transmission?
