Dash Board Controls Not Working on 1991 300 SE

[1991 300SE Owner]

Hi guys - need some help on my 1991 300 SE. None of the indicators on my dash board are working. My gas gague shows empty, the RMP's don't work, no speedodometer, no oil pressure. I noticed this when I was half way to work this morning. The only thing that did work on the dash was the 'economy' gague when I presssed the gas pedal. It's pouring rain here so I don't really want to pop my hood. Does this sound like a blown fuse? Or something more? It was fine last night, as my sensor was on showing I need to replace my wiper fluid and my the sensor saying I needed to replace a light was on. But now those are gone too. I put my Emergency brake on and no light for that either.

Any ideas? I'm a little leary to drive the 10 miles home if it might be a serious problem and will damage my car.
