Hi,
been awhile since we communicated.
I have done a whole lot of trial and error with this situation, changing, coolant sensor, ambient temperature sensor, aux fan relay, compressor relays and to no avail, until I had my friend put on ac computer and the code that came up was solar sensor, I did loads of research and couldn't find much information because apparently these do not go bad very often. I even had BMW try and diagnose, and they couldn't figure it out.
Finally I found the location in the front window down in the dash.
I hooked it pulled it out and exposed it and I started to get more response from system.
Changing this thing is to pull out complete dash and cluster which I can't afford so I am buying a new one and splicing to old wiring, should work.
But that was the whole problem,
thanks for your help figured you would be interested in final conclusion.
Danny
