[V8] Electric window problems

[Daniel Hussey]

Thanks Steve,

Been off any Audi lists for a while since selling my S6 Avant a year and a
half ago.  Drove my Porsche 944S2 as a daily driver for a while and my
beater Jeep in the winter.  I bought a 2004 Volvo V70R about about 6 months
ago, and that's been just awsome.  Closest thing to an old Audi isn't an
Audi anymore.

But, back to the window problem...  I just went down and both switches
function perfectly fine.  I tested them by plugging them into the driver's
side window plug and the driver's side window went up and down fine with
both switches (the one pulled from the driver's side cluster and the
passenger side).  So, there's definately something else amis here.  I don't
have anything to test continuity between circuits or even how to do that if
I could, but seems like one half or that whole thing isn't getting power for
some reason.  Any ideas where I need to be looking next??

The previous owner says it was erradic for the last six months.  But, I just
went down there and now I can't get it to go up OR down!  Before it would go
down, but just not back up.  I've checked all the wiring in the door jams
(where I know they often get kinked and break), and I've tested the window
regulator which seems to be working fine.

What am I missing here?  Is there no relay or anything else that could be
causing the problem???

Later,
Dan
