How do I fix the outside air temperature sensor

Asked by Oct 27, 2015 at 09:47 PM about the 2004 Buick Regal

Question type: Maintenance & Repair

I have a 2004 Buick Regal. For the past couple months, the outside air temperature has been off (saying 50F when its really been 60-70F. Today it went down to -38F and only up to 0F. Because this, the A/C won't work (since the car thinks its -38F outside, it blows out hot air for 60F). How do I fix this?

This sensor is just behind the grille. It has a two wire plug connected to it. Check the plug. If the plug is good, replace the sensor. HTH. - Jim
