Xantia HDi. (Temperature Sensor)

Can anybody tell me where the Temperature Sensor ( for outside air temp.) is situated on my Citroen Xantia Mark 2. Mine is only showing lines acres, and the letter C, on the display. so I presume the actual read-out is working & the problem must exist in the sensor (wherever that is situated).

On a Mk2 Xantia it is on the underside of the Left hand door mirror (on a Mk1 it was on the RH mirror).

Im sure it isn't in the left hand mirror on my MK2 Xantia, is it a little dimple that sticks out of the bottom (like on my 306) or is it behind the glass?

I have seen a mates xantia wiring diagram book which shows the OAT sensor located up over the blower fan unit ......I was interested as my OAT readout shows 45 deg and I have a blower snag. i was wondering if there was any connection. My next step is to read the codes to see if it shows up anything. The voltage on the light orange wire ( no 16 ) to the blower motor should go up and down as you move the slider but doesn`t.....it stays at approx 11 volts .....the blower will only run if switched to full. the wire comes from the aircon ECU but some on this forum think that some of the temp sensors, if duff, can confuse the Aircon ECU. .......any ideas ??
