Same here-I never even tried to get the AC running due to the empty,
melted relay socket in the glove box. Whoops.

Yes. There is a relay behind the fusebox that gets really, really hot.
Can't say exactly which, but I seem to recall it's the 2nd or 3rd from
the left with the glovebox removed. Not sure whether the relay in my
case was defective, but I DO KNOW it was melting its socket. In my case
when I slowed down the whole interior of the car filled with smoke and I
quickly removed the relay (which was useless in a car with AC system
removed). Don't have the IST documents in front of me, so I'll let
someone else chime in...
