We have a problem at our 2001 2388 combine. The air conditioning doesn't work at all and we can't control the air fan speed wich is high. Checked the potentiometer wich controls the fan speed 2.5k is ok but there is no current 0v. That is how it should be? Also how we can check the pressure sensors ? The compressor isn't clicking but if we strap him with a wire from battery the air works but still no control. Checke the pressure and it's ok.
