Hit switch and heard very loud pop and then the engines revs extremely high

The headlights won't go off and it just started this morning.

other things like wipers slowing from 111 speed to 11 speed at stop and 3 blink signal function doesn't work either. Nor does the interior light (on with door open) and (slow fade off when door shuts) work. if you move sw. to auto, it just stays on "all the time".

About half or more of the time now my driver door when I get out and close it or get in and close it and let the close-assist feature suck it shut, it takes 5-10 seconds for it to respond and then pull the door shut. What could be causing this?

I don't know if it matters but my car is equipped with keyless-go. Anyways, I think it is common on this car or any S-Class, but there are two buttons underneath the lip on the back of the trunk/above the license plate. The button that opens the trunk doesn't usually work. I will push it once and it will A) open fully B)open partially and I will have to push the button once more or C)it will open 1cm, push it again and it will open to 1in, push it a third time and it will open fully or D)it will open 1cm, push it again and it opens to 1in, push it again it opens 2in, push it a fourth time and it opens all the way. I have a problem with all of the buttons on my door handles as far as they don't work correctly either. Is this just an overall issue with my keyless-go system or is it something else?

Since I have had my car (100,128mi and currently at 113,800mi) the lights behind the door handles on the passenger side of the car do not work. All other lighting such as behind the passenger door handles as well as the foot wells work. I did research a while back but forgot what I read but I was sure this meant there was a larger underlying issue. Any similar stories or know what may be going on other than "replace the bulbs, take it to the shop"?
