My exterior temp readout on the climate control is not showing the right temp..

Does anybody know where that sensor might be located or how to fix this problem..
Maybe it got little dusty and is not reading properly?

Any other suggestion would be appreciated..

Thanks in advance.

Open the hood, and then look just behind the front grill and in front of the radiator. About half way down, you'll see it. You can try disconencting it and cleaning the connection and see if that works. If not, it may need replacement.
