Wrong Outside Temp

Any idea why my 99 CV would start displaying the wrong outside temp? Where is the sensor located?

i have the same prob and cant figure it out

yea i gotta 93 CV LX and it shows -32 at 40* temp haha

my 92 does the same thing im trying to find the scensor to clean it or replace it

I had the sames problem with my 92 marquis, The problem was a bad connection in the back of the instrument cluster. It first started acting up when I had the A/C running and shorly after if give me a -40 reading.
