Climate control
Hi all
I'm not able to turn the EC off, no matter what I turn on or turn off the light won't come off... Will this mean that the system is out of gas?
Cheers,
Sondre

Check your codes on the climate control unit. It's easy to enter the diagnostics of this unit. If you have a code for the clutch ( like I did your hosed)
I got the code for the clutch which set the EC light.
By the time it forced my system off, the compressor seized up.
I fixed mine my self and it has been working great in the AZ desert.
Luckily I got my compressor from TX for 250$
Good luck.

There are two parts---reading actual values and reading faults. You need both to fully understand what is going on.
READING ACTUAL VALUES:--------AC must be running to retrieve actual values!!
Ignition---position 1
Press the auto button and set temps to 72F or equivalent C
Press the Rest button for 5 seconds or more
The left side of the display will show number"1" and a value for In car Temp
Then press Auto again for the next number and corresponding value
Keep pressing and writing down the numbers and values till "12"
To end the process press Rest----you are half way done!!
READING FAULT DIAGNOSIS:
Ignition in position 1
Set Left Temp to LO
Set Right Temp to HI
Within twenty seconds simultaneously press the rest and EC for more than 5 seconds
The screen will flash "dl R"
Now press the right Auto button one at a time until all faults are displayed and recorded
All faults must be read out before they can be cleared.
To clear all faults press both auto buttons for more that 2 seconds and a "d" will be displayed on the left and "FF" is displayed on the right
Now go back and reset you cabin temps---ignition off------end of test
Good Luck and after clearing the faults there will be no red light on the EC button, but will return if you do not fix what is faulty.
In your case that will be late summer, Oh well

What does these values actually mean?
Well, I'll gotta give it a second go then. I'm not too worried about losing the functionality of the AC but it would be nice to know what's wrong with it...

Wow! Thank you!! This wasn't bad at all, I do not care to much about the AC but I will get it fixed anyway. Nice to get things sorted... I do not see any hints to having a bad coolant pump in everyday driving, the car is always "cold" (beneath 80'C). But if the codes say so I should probably change that too.
What is the main purpose of the sun sensor?

Ah, more like a trouble-maker this sun sensor then? I'd like to control it myself at all time 
Yea, looks like it's time for a quick stop-by the local workshop to get it filled. Hopefully it's just empty...?

Ah, it surely plays a bigger role in controlling the temp than I thought. But I am rarely bothered with extreme warmth here up in cold Norway so I'm not sure if I should bother change it...? Th AC-system will be fixed though!
