I can't find an ECC unit (automatic climate control)for my '85 760Turbo.
Mine works butsome plastic is broken soI can't slide the little control arm. The wiring and all other parts are fine, but the only choice is to replace with a new unit.
I've checked my local parts stores as well as 7 or 8 different online stores, andI check ebay daily.Anyone have a clue where I should look next?

 

Have you tried: http://www.erievovo.com/.

I have been told they do a lot of used parts. I am from the UK so can't vouch for them personally. I was also told that they are slow answering email but good when you telephone.
