Loss of Fan control from Climate Control, 87 5kcstq

[Motor Sport Visions Photography]

The subject line pretty much tells all. My climate control blower fan is
doing the opposite of the usual failure (the fan is only ~3 years old
and runs fine) in that as of yesterday it started running at full speed
regardless of the CC setting (yes, it even ran full blast on the "off"
position). The problem is intermittentent (aren't all Audi electrical
issues?). The opposite problem/cure seems simple, change the blower
fan...this no doubt gets more involved. I know there is a speed control
box someplace and will sit with book-o-Bentley and properly troubleshoot
this when I have time and will report the fix to the list...I was just
hoping there could be a BTDT shortcut I could follow.

TIA for thoughts and suggestions.
