A while back my climatronic went a bit hay wire and thought it was -4 deg on a hot sunny day so no matter what i did the A/C wouldnt turn on as the air out side was below freezing
So I bought a 2nd hand replacement . . . ..
It knows the correct temperature and will turn the A/C on but throws a million errors every time its turned on (not really an issue) and only has 2 fan speeds off and flat out
So I bought a 2nd hand replacement . . . ..
It works great . . . no errors ,correct temp reading and has all fan speed settings BUT will not turn A/C on

Anyone know anything about fixing these suckers or where I can get (another) replacement to test out . Ive tried swapping the front controls with the main pc board but with no success and clearing error codes and running self test modes has the same result .
