Sleeper light stopped working

Freightliner Cascadia 2016
The sleeper lights stopped working and some switch keys in the dashboard stopped working and the check engine light comes on .
after I finished driving last night I found out all sleeper demo light not working so I off the engine then I waited for 10 minutes then I start the engine again
The check engine lights come on then some switch keys in the dashboard became out of service then I off the engine until the morning to make another try morning time To make sure if something like wire wet should get dry until Morning
And in the morning I started the engine and I checked the light everything the same nothing works ..I'm confused .
I drove my truck today with the engine light on but the speed is normal I can go 65 I can go 70 there is no speed drop down with engine light on .
If somebody has an idea about this electronic issues can help me for this

 

ohh o.k. I took out the control panel trying to find something like this I didn't see any sign coming from the AC
But you think do I need to change the control panel keys the one you showing in the pic you think should work normal if I do . Or if I bring electronic cleaner spray should help

 

I did the way you told me and now it's works perfect
I just clean it by the electronic spray then put it back again
Thank you I appreciate it

 

I did the same you told me just clean it then put it back again and works perfect
Thank you appreciate
