98 Buick Century, Outside Temperature Sensor
I own a ‘98 Buick Century Limited with automatic climate control that has an outside temperature readout on the screen. Of late, this read out has been erratic, showing 50 degrees when the outside temperature is 32 degrees. Where is the sensor located? Can I replace it myself? Or, is that the problem? What can I do?

Yes, you can replace it yourself. It’s located in front of the radiator air baffle on the right side just behind the front bumper. O-yes, you should know that the software/program for the temperature sensor does not update the display unless the vehicle is driven over 20 MPH for more than 3 minutes. If the vehicle’s speed drops below 20 MPH during the first 3 minutes the sensor display will not be updated. Therefore, if you take your vehicle out of a warm garage and do not get above 20 MPH within 3 minutes you may find that the readings are not updating correctly. You may want to check that out before you replace the sensor.
