So after few days of fighting with ac in my volvo I give up .
So my ecc gives me 2-1-4 code (servomotor works too long ) .
What i checked for this moment
temperature sensors both..(about 8 kohm in 25 celsius )
ECC for broken solder joints .
Servo motor inside . (motor spins ) pcb looks good no broken traces.
Flap if it's move freely,
I ask for some sugestions what more i can check ?
