Where is TempSensor A/C on S2 92

[ceazys2]

hello, I search where is the tempsensor on evaporator, because my A/C compressor run all the time and the air temp is too cold.
excuse me for my english, i'm French.

on the evaporator there is no temp sensor, some temperature sensors are in the klimabox, the outside temp sensor is behind the front bumper, than there is one in the dashboard (automatic air conditioning only), and one is in the light in the roof, and one in the engine water hose.

if the A/C don't have tempsensor in evaporator, why the compressor run all the time and the air flow is very cold where the outside temp is inferior has 25°C. i have mesured the air flow temp : 0 or 2°C ????
my A/C is a automatic air conditioning.

If you press the snowflake button, the compressor does not switch off? Try with the diagnostic on the AC. Press and hold the interior air recirculation button and then press the up arrow. On the left screen it will show 01, and press the interior air recirculation again. This will show the faults. Write all the numbers it shows on the left screen.

I don't have the last A/C i have the first. When the A/C is in mode ECON the compressor is off, and in mode auto the compressor is on. and in memory non fault.

Where is the problem then? The air is too cold? What happens if you set somethng like 23 degreees?

You can still run the diagnostics on the old type ACC...
press and hold the outside temp button, continue holding it and press the off button. release outside temp, release off, and you will see 01, which is channel, press outside temp again and it will read any fault codes in the system (00 indicates no faults found)
red (temp up) and blue(temp down) scrolls through the channels...
