power windows/sunroof

[snates]

Hi, I own a 1995 audi A6. For the last week the windows and sunroof would stop working and approx 10min afterwards would work again. This happened constantly all day long. Now niether work and there is no load on the battery gauge when trying to open windows or sunroof. All the fuses under the hood near the firewall seem to be ok, and the general fuses in the car seem ok. I cannot locate a fuse or relay that controls both. I thinks its a relay because before this problem it worked then stopped then corrected itself. Is there a fusible link, relay or something that isnt in the firewall fuse box or in the car fuse box? Thanks
