It could be your Ambient Air Temperture Sensor which is usually located behind the grill near or on the radiator mount. There is a testing procedure to diagnose the sensor but you will need some tools like a DMM and jumpers etc. just let me know and I can post the info.

I currently own a Multimeter.What are we checking for, ohms?

Yes at the Sensor. I have the tables where they should be to get a correct reading. Ill post it when I get home. I dont have the info here on my work Desktop.

As promised here are the readings you should have at the sensor when testing.
