I was going to ask you how you did all that then I remembered you had
the later 140, I have the earlier version which I dont think works the
same as yours.

Actually, having spent an hour or so today diagnosing my 140's HVAC, I
have to say it is a real delight compared to the Type III in my olde
300D. You just push a couple of buttons to enter diagnostic mode, and
it tells you the values for every sensor, module, and whatnot in the
system. All seven (or more) temperature sensor values, refrigerant
pressure, blower motor voltage, and so on. Then the manual tells you
where everything is, what the values should be, and how to test it, so
diagnosis is just a matter of knowing how to use a multimeter.
This compared with chasing vacuum leaks all over creation. The only
downside is that you can't fix a 140 with a golf tee. And later 140s
have a much simpler ACC interface.
It looks like I've got a bad blower motor regulator. This seems to be a
common problem; note that the eBay car has a brand new one.
