The outside temperature display on my 147 JTDM was constantly reading anything between -14 and -35, i have changed the sensor in the wing mirror and now it shows the opposite, anything from +25 to +43. Connecting multiecuscan shows up fault code B1973 Climate Control Compressor, saying there is no signal.

Any ideas please?

i'd check the connections from the temp.sensor to the controller box in the drivers door, and the round connector in the drivers doorsil. Sometimes the pins are corroded, and unplugging/plugging already helps
