Climate Temperature Sensor

I am having problems with the outside temperature reading on my climate control panel. It shows 27-28 degrees all the time. This is a '99 Intrigue with electronic climate control. Where is the outside temp sensor? Does anyone have any idea if this could be the problem or is there something else that would cause this? Thanks for any help.

The part is called an ambient temperature sensor. GM part number 10248414. It is located at the front end of the car in front of the radiator more towards the passenger side. You'll see the wiring harness, the electrical connector and the sensor.

It sounds like the sensor is bad. GM List price is $8.81.
