that sounds abit more serious then a sensor. check the fuse for the climate control unit or the recirc unit. a sensor would stop the ac but you would not get the flap error. unless the motor has failed and that is why the sensor is getting a false reading. check the fuses see if theres any blown.
 
No blown fuses. I was measuring voltage and there is none on fuses number: 21, 22, 23, 24, 26, 27, 32 is this normal
 
G263 I believe is a common source of failure. I see that it is shown as "Open circuit/short circuit to positive"

I have had the g263 fault which is a dash out job to change the sensor BUT that is the only fault that came up. I think i have the log similar somewhere on my computer. it does stop the ac working but would not impact the motors from operating as they will still operate in eco mode so unless something else has caused the faults i cannot see that single sensor causing all those faults.
I would look elsewhere before taking the dash out to find its not that sensor. by the sounds of it you cannot direct the flow of air. I would look at the climate control unit being faulty or a fuse/relay.
 
I measured the G263 resistance and it is too high, I believe the sensor is faulty. It is easier to change it on LHD. The additional errors occurred after measuring of G263.
It could be, that I shorted sth.
For starters I will order a replacement G263, after that I will try to replace climate control unit display.

Andrew recently changed the G263 without removing the dash, the first to do this on a RHD car - http://www.a2oc.net/forum/showthrea...nder-without-removing-the-dash&highlight=g263

Guys, can please someone explain. Besides the issue with A/C I had problem with brake pad wear alarm, I found the cable broken somewhere in the midle and after erasing ABS error I have no errors for A/C. Why? A/C is stil not working.

I can't help answer that mystery. But have you had your A/C regassed, maybe it could be something simple like refrigerant needing replacing or a leak that needs fixing?
