top/fuse problem?

[Perfectlap]

possibly, I don't have the fuse chart with me but if you pick up one of those fuse checkers from Autozone or Pepboys you can see which fuse doesn't light up.
and replace the fuse with one of the spares on the bottom next to the yellow fuse removal tool.

But I don't think this your problem otherwise none of the gauge cluster indicator lights would be lighting up and not just the e-brake light.

If you've checked all the fuses with the light and pushed in the top relay to determine if its working (windows going 1/4 down automatically) then my guess is that the parking brake switch is blown.

Check out Renntech.org to see if replacing the switch is a do it yourself job. That could have saved me $90. You'll have to go to the Porsche parts desk or order it online.
