Automatic Climate Control

Hi all,

The display on my automatic climate control unit is faulty. Sometimes
it comes on, sometimes it doesn't.

The other weird thing is that sometimes it displays the temp outside
and sometimes it doesn't and just shows a Celcius sign. Has anyone
else had problems with this?

I feel like the heater is not working properly at times because it is
not displaying/getting the temperature from the outside correctly.
What could be the problem?
