Fuses and Electrical
What supplies the electrical power for the garage door opener and compass on 2010 E550? My indicator lamp does not flash when trying to program my opener, and my compass isn't working either. However, vanity lights and overhead control panel lights are working. How can I troubleshoot?

There is one fuse that supplies power to OCP which in turn powers mirror, f17 @ front SAM (engine compartment). You can try pulling it to reset mirror electronics, then move on to electric connections. See attachments.
