My climate control has been running about 8 degrees warmer than indicated and blows warm air except on LO. In accessing the head unit codes, it says that the G 109 Ambient Temperature at Fresh Air Blower is -59° C. That would possibly put it in heating mode all the time. OK, where is G 109? I've seen other sensors in the center dash behind the radio or behind the glove box, but where is this one?

Thanks,

No, that's the exterior one. That one is sending correct temps. The one I am looking for is inside the car probably near the heater box or fan. I think.

From the list of Climatronic head unit codes:

56 Temperature in deg C, from Interior Temperature Sensor, in Headliner (G 86)
57 Temperature in deg C, from Interior Temperature Sensor, in Instrument Panel (G 56)
58 Temperature in deg C, from Fresh Air Intake Duct Temperature Sensor (G 89)
59 Temperature in deg C, from Outside Air (Ambient) Temperature Sensor (G 17), front
60 Temperature in deg C, from Ambient Temperature Sensor At Fresh Air Blower (G 109)

The one posted is code #59; I am looking for code #60.
