multifunction switch working now on my 90 200

[mike posner]

No replies to my two postings, but got a 3 terminal
replacement sensor to replace my third  failing  four pin 
sensor, and  re wired the sensor and new  plastic sensor housing  with new snap in connectors. Still getting  no engagement of compressor clutch, no current to clutch.
.  So , only about whole lot of things that can interrupt
the ac clutch  from getting current, but my sensor wasen't one of them nor the low limit switch. I rigged a fix for the recirc flap which had broken its perch. 

I'm getting  some weird lights on the self diagnostic
program  on the ac control head.  This Audi ac  is  very complex  and the  time it takes to trouble shoot  all the
sensors, wiring, relays etc is unreal.  Certainly teaches
one patience.   Oh I almost forgot, the temp guage works great.    MP
