Default 1998 SLK 230 Electrical problems

I'm posting this anywhere I can....help
....help
I hope this is the right form... I'm a NUG here (New Useless guy)

I picked up a 98 SLK230 last year and it's been great. A couple small problem like a few dash lights out and the alarm seemed to be intermittent.

It's got 42K on it and hasn't seen a winter to the best of my knowledge.

The other day I decided to take it to work. I jumped in and got to the end of the drive way and turned the windshield washers on...but they didn't work. Nor did the wipers, turn signals, power windows, locks, and I find out the top isn't working either.

I've checked all the fuses and the grounds and find all seems well. I popped the top of the control box to see if anything was loose but all seemed to be find.

I've got a CD with the wiring diagrams but I seem to be overlooking something.

Could it be the control box unit itself? Am I missing some relays

All the fuses are fine. There's power through all the fuses.

The four terminals at the rear left fuse box (eng. compartment)all have power to them (2 all the time) the other two with ignition on.

I followed the wiring harness to the right side under hood to the box that holds the control box, and whatever else is in there. There;s 4 or 5 fuses there and they are fine too.

All the wires seemed to be plugged into three (3) large modules which look like ECU's.

Are there breakers or modules in these boxes that can be checked?

Thanks
Colin
