New Ignition Switch fixed all the electrical gremlins

If I'm wrong...then I guess I'll look like a big fool!

It started with the DSP control went blank at the beginning of this week. Then mid-week, the airbag light illuminated on the dash, then the rear sunshade started moving real slow, then stopped working.

Then the MLF steering wheel buttons stopped illuminating and when I went to blow my didn't work. I then remembered that if you pull down the sun visor and open the cover to the mirror and odd things happened...the culprit is usually the ignition switch (yes, odd connection). I even mentioned this back in Oct/2007 after reading about it on one of the e39 forums:

I know that the sun visor test sounds I made a short video this evening after work just to show how unbelievable the connections are of the components that are affected by the ignition switch. And is not a prank (that's why I waited until after April 1st).

You can see the steering wheel move up/down when I open the mirror cover on the sun visor, and the interior lights fade on/off...and the radio shut off:

Okay, got a chance to tackle the ignition switch this morning in the E38...and as you can see in the NEW video...all the previous issues have disappeared and everything works correctly now.

It took about 1 hour to do the job, not because it was difficult...but taking the time to disassemble and reassemble stuff, making sure you put stuff back correctly, always drop a screw, or need to go get another tool to do the job etc. On a scale of 1-10...this is probably a 2 or 3.

Here's the video that shows everything is back to normal after replacing the switch:
