power windows and sunroof on 1992 Audi 100

My power windows and sunroof quit working is it a relay or fuse if relay could someone tell me which one.

It could be either or both or neither. You really need to have someone inspect the problem. Both systems are electrical with switches, fuses, relays, circuit beakers, motors, wiring etc and any of these components could be the cause.
is there a r4elay that controls all windows and the sunroof and if so where is it located?
