Does not detect the exterior temperature in the table

Hello everyone the previous problem I had with the alternator and the tension of the belt! Solved !!!! Thank you.

And now another, in the picture of my Opel Astra Merit of 98, the date, the time, and the external temperature appear, well because those digits do not appear, I mean that of the outside temperature, the date and time if they appear.
Let's see if you can solve it.
Thank you, and this forum is really the best, thank you.

Hello, check the sensor found in the front bumper just in the center in front of the radiator; Good luck greeting
