Here's another tip for running the flap calibration routine. If you press the ECON or A/C button at the same time as the button which directs the air straight at you, this will initiate a calibration of the FLAPS. The digital temperature display will show all segments, and the computer will do a 2 minute calibration (you'll here the flaps moving).
It worked for my EOS 2007.

Just a thought

Thank you for writing this tutorial, i managed to save quite a lot of money.
However, i used a special potentiometer cleaner spray and i advice everyone to use it, it cleans the dirt and also has a special lubricant in order for the potentiometer to slide correctly.
Cheers!

I think this might be the problem I have. My issue is that my AC is now shot. Could this problem lead to that? I ask because my mechanic is hesitant to change all the main components of the AC (compressor etc) when it’s still throwing a code that the environment controls are off (something they are insisting u go to the dealership to confirm which seems like overkill). Because I am not a mechanic and I will not be doing the work myself, I can not confirm the exact codes it is giving them. However, I wanted to determine whether fixing the larger components is even worth it when this problem would still exist. I suppose I could have them go ahead and do what you suggested to see if that clears the code. What are your thoughts? Thanks in advance for your help!
