Anyone replaced an evaporator in an Audi 100?

[Don Thompson <pupcrnch@bellsouth.net>]

Has anyone replaced an evaporator in a 92 Audi 100?   What is involved
and do I need to remove the dash and the center console?  ALLDATA says
to remove the glove box and the four bolts on the firewall and that's
basically it.  But it's not that simple!!  I followed their procedure
and am no closer to getting it out than before I removed the glove box.
Any suggestions would be appreciated!!
