I've got a '95 E320 and this afternoon I turned the car on and noticed that all the alert lights stayed lit long after they normally were supposed to be lit. So I turned the car off, turned it back on, and everything was fine. It's a hot day so I put the airconditioning on.

About 10 minutes later, while I was driving along at about 10 miles an hour, all of the needles and dials on the dash board went dead, as if the car'd been turned off --- everything except the speedometer. And at the same time, an obnoxious electrical buzzing sound that I've never heard before --- like something was shorting somewhere in the far left side of the dashboard --- started and kept going.

I noticed that if I turn my left or right signal blinker on, or, turn the hazard blinkers on, the buzzing immediaately stopped (but the dials on the instrument panel of the dash stay dead). And then if I turn off the blinker, the buzzing immediately resumes.

When I got home I checked the fuses and they all seem fine. I turned the ignition on without turning the car on, while I had the hood up, and the loud buzzing sound is coming from the far back of the fuse box, behind the fuses. I can feel the whole metal enclosure vibrating when I touch it.

Anyone know what this is all about?????

Is this going to cost a lot of money to fix???

(Car has 134k miles by the way)
