I took my 87 300SDL in for a headlight change and caliper change.

Before hand, the left turn signal worked, but the green dashboard arrow didn't blink & there was no clicking-on/clicking-off sound in the cabin.

After the repair, the dashboard is dead and I have no left or right turn signals. None of the lights on the dashboard work. For example my low washer fluid reservoir indicator is not on, even though my reservoir is low.

It was closing time at the shop. At the time, all I noticed was that the turn signals weren't working. I hadn't immediately noticed the whole dashboard was dead. They poked around the fuse bay, rejiggered fuses & relays, & checked some electrical connections there, and didn't turn anything up.

As I was driving around, I moved the dash light rheostat. At first the light over the LCD adjusted, but then the light went out.

The car's odometer has been dead for ~6000 miles too (approximated via fuel logs).

Anyone have any ideas about where problems might lie? What things would you look into?
