[V8] V8 Sunroof Problem

[Brad Hartman]

First of all, this is Brad Hartman, long-time member of the V8 list.  I had
to resubscribe under a different email address because I became unsubscribed
some time ago when my mailbox became full.  All attempts to resubscribe were
fruitless because it said I was already a registered member, but then I
could never get the digests again.  I reported this bug to the webmaster
some time ago but have not received a reply.

Now, to my problem.

My sunroof is not operating.  I opened the access to it and discovered that
there is no power to the sunroof via the Red and Black wire that connects to
the sunroof mechanism via a connector.  I applied 12 volts to the connector
and the actual sunroom mechanism works fine, so it's not at fault.

There is no fuse for the sunroof, just a relay (#1, I believe).  This relay,
however, also operates the power windows (I think) which all work fine, so
I'm guessing the relay is OK.

Any idea where that Red and Black wire goes from the sunroof area?
Somewhere there's an open circuit, I'm guessing.  I have the Audi manual
(hundreds of pages) including all wiring diagrams, but it's really hard to
determine where the wires go from reading this.

Any suggestions?

Thanks
