climate control temperature dial problem

[Philsla]

I have a problem with dialing high temperatures on my climate control system. When I turn the dials, the temps shown jump up and down but mostly down. If you are really patient, you can get the temp up one click at a time......sometimes. The A/C is on when the A/C button is off and vise versa. The blending settings work switching from front to floor etc and the fan speed goes up and down just fine.

I did replace my battery the other day but it was doing it before I replaced it.

Here is a link to a video to show an example: https://www.youtube.com/watch?v=o3V2ETcCsMo

Any suggestions welcomed.
