My Daughter is in Missouri this week in her '94 E320, has no electrical accessories (wiper, blower, windows), radio goes on/off with the key.

Unfortunately, I can't get to my service manuals, ... and need some troubleshooting help.

Where to look first? I thought ignition switch, but she claims that the radio is turning on/off with the key, ideas?

TIA.

Fuses or grounds seem a good bet; don't just look at them, ohm them.

Unless stated otherwise, any question I ask is about my greymarket 1985 380SEL.

Multiple fuses at once? Multiple grounds at the same time? Neither sounds likely to me. Thanks though.

One ground can control many devices; they don't all have their own seperate grounds; they share them.

According to the electrical diagram I have, the power windows (convenience control module relay), window heaters, blower motor, etc... all share the same ground, designated "W1" and located behind the instrument cluster.

All is good again thanks to a forum friend, and she's on the way home.

Fuse #2.
