Good Snowy Sunday Morning,

I have done a basic search but did not come up with anything. If such a thread exists please link it and I apologize.
Best I can describe the issue is "my illumination dial magically scrolls on its own". The dial/wheel of course does not move but the cluster and hvac illumination changes intensity randomly on it's own. I typically have it set very low as the illumination bothers my attention. At first I thought it has to do with ambient lighting but that is not the case. With the dial staying in the same position sometimes while driving on a sunny day the illumination goes to fully lit and does not go back down until i scroll the wheel up/down several times. Other times I would start the car and illumination is completely off again until I scroll up/down several times.
Anyone encounter this issue?

 

Remove the switch and illumination should go to its highest level and if it stays like that then the switch is bad.

 

thank you
any instructions available on this procedure?

 

is this it?

 

thanks
how do i disconnect the dial?
