Power Rear Window Sunshade problem on my audi a6 c4 2.8 v6 quattro
 

Hey guys! I'm new so I'm not sure if I'm posting on the right place but here's my problem:
The rear sunshade doesn't work. The car is a 96' A6(C4). When I press the button I can only hear one click (sounds like a relay to me)and after 5-10 secs another one. The motor doesn't make any sounds like it's working. Has anyone tried to fix this before, how can I access the sunshade motor, do I have to take out the rear seat...? I really could use a tip or two.
Thanks!
