The ignition switch is #2 in the diagram below. There is a great DIY write up on www.e38.org on how to replace the ignition switch (the procedure will be basically the same on the e38 & e53 since they have the same design architecture...just do a page search [Ctrl+F] and type "ignition switch" as your search word to skip quickly to the DIY link):


A failing ignition switch can cause a lot of weird seemingly unrelated electrical gremlins...other than the fact that they all are actually related to the ignition switch in that the ignition has to be "on" in order for the electrical components to work. In the video below...you can see some of the odd things you can sometimes get to happen by reaching over, pulling down the passenger sun visor, then opening the mirror cover (while the engine is running). If you can get the gremlins to appear....then you can pretty much bet that the issue is the ignition switch. If nothing happens...then it could or could not be the ignition switch. If the latter occurs...some have replaced the switch with success...and others have replaced the switch and the symptoms remain.
