Not ignoring you; I just haven't seen this problem described. You could pull and reinstall the fuses for that system, or alternatively disconnect the battery (negative first) for 5 minutes or so, to try to get the system to reset. If you disconnect the battery, see post 14 at http://www.benzworld.org/forums/w220-s-class/1302190-ive-had-2.html#post2216730 - you could have to reset some things. Though written for the W220, the resets work for many more models.
