'02 A6 AC stopped working
The AC in my car suddenly stopped working. I don't think the compressor is
moving at all. There is no change in idle speed or sound from the engine
when I turn the AC/heater unit on and off. There is a fuse marked heater/AC
or something like that but it's not broken and I guess if it was, the heater
unit would not work at all. I think there is an electrically operated
"clutch" that connects the compressor to the drive belt. Could this thing be
on a separate fuse? How do I find this "clutch" and the wires that controls
it? Anyone know how I can troubleshoot this?

If your AC has a display, you will be able to pull the fault codes from it
by pressing a combination of buttons. Unfortunately, I don't know what these
will be for your model but a search on the internet might help you.
Good luck

Try pulling out and putting in the relais which is in the fuse box as well.
It helped when mine went dead in Italy last month.

First check that the AC compressor belt hasn't snapped - it'll be down the
front of the engine.
Second engage the AC & then feel the AC lines - (usually aluminim looking
things routed around the side of the engine bay) one should go cold pretty
quickly & you should see condensation. If it does go cold then the AC is
working & try changing your cabin pollen filter - that worked for me on an
A4 a couple of months ago when we thought the AC had died.
If the line doesn't go cold then either the compressor/compressor clutch has
packed in or you have a big leak & have lost all your AC fluid (in which
case don't drive the thing too far). The fluid also acts as a lubricant &
without it the compressor will sieze if it hasn't already.
