Occasionally when I go driving in my 156 (made in 2003), the infocentre alerts me to the possibility of ice on the road due to an outside air temperature of -21 degrees C, or sometimes 42 below (no pun intended
: 42 Below being a brand of Kiwi vodka, 42below.com).
Apart from the loud BING sending shivers down my spine (I used to drive a Stilo, where BEEP BEEP BEEP meant impending doom), this is actually more of a problem than you think; the air conditioning won't turn on, which means demisting the windscreen and windows takes a long, long time as the thermostat is broken, so there's little heat from the heater. The actual air temperature is around 8 degrees and it's damp, so I do need the aircon.
Then of course like all good Alfa Romeo electrical problems, it rights itself and displays 8 degrees, the aircon comes on, and most is right with the world (would be even better if the heater worked, I will replace that thermostat soon, I promise).
Has anyone had this before and does anyone know, please, where is the most likely cause of a bad connection to the exterior temperature sensor? For a start, is it on the left mirror or the right (both have a small bump below them), is it likely to be a broken wire into the door, or is there some multi-plug somewhere that I need to check and clean? Or finally, is it likely to be the sensor itself at fault?
