Thanks for the direction. My electrical skills are limited to cleaning contacts and thats on a good day. I know where the Klima relay is located and you can see that my options are limited to replacing it with a new one (129.00) or a used one (pointless since I have a used one already) and I was thrilled to find someone who offered to inspect these ancient electronic components and report back for free. Is there a schematic for the Klima because I dont remember it having any inscriptions on its side.

Re tempmatic: I have that link and actually sent the guy 5.00 bucks once-- its a great write up and worth the money. I replaced a lot of elbow behind the glovebox. Currently I have a temp wheel that responds to on/off signals but nothing in between. So we're testing things. I have control of my vacuum pods and the PO replaced the whole tempmatic unit with a used one, so Im looking farther afield. I might still have a bad air fan: I replaced the first one and was changing air when I started, but I havent actually seen the tube that goes from the visor to the fan. It could be missing.
