Answer
Hi Goran

Now I understand why you wanted that.  You should be able to control the temperature with your heater button (the one that has the blue and red lines).  What may be happening is that your actuators have lost the programming or have gone bad.  We can check for the programming by just disconnecting your battery and reconnecting this should reprogram the actuator motors.  If this does not work then you need to see if the actuator motors are moving properly.  This vehicle has temp. sensors for the cabin this may be faulty also.  Run the test and let me know I'll try and help you.
