My outside temp gauge is way off
 

for the last 2 weeks its been way off if its 50 outside it says 95 etc. how do i correct this? its annoying.

it isnt reading celcius is it? I doubt it, since it would be 122 F if it was saying 50 C. I have no idea, considering I dont have it.

Check the connection at the sensor. If it's ok, replace it.

The sensor is located at the front of the car. Actually in front of the radiator.

First I'd aim for Lowriders suggestion and hope the F/C button got pressed by mistake.

Take a hair dryer and pass it over the sensor a few times, look for a rising temperature on your climate control display. If no change, sensor has probably failed.
