Dead instrument panel in 2002 ML320
Also no instrument panel lights, no indicator or warning lights, and no HVAC controls. Fuses? BTW, the truck starts and runs fine.

I replaced fuse #5. That fixed all the problems, I think. I turned the truck off and restarted it, and everything was dead again. Hmm...
So, what's Plan B -- the next step? Ant thoughts?
I updated my info, BTW.

Purchase at least four 15 amp fuses. Key out of ign., remove and replace fuse #5.
Open hood and locate the Coolant Cir. Pump near the battery and remove the two wire connector. Start the truck and shut it off (maybe a few times) and see if the fuse blows.

I tried a second one of the five 15A fuses I bought and walked slo-mo through ignition and startup. It blew while I was admiring the full set of warning/indicator lights. I will do your suggested second step either shortly or tomorrow morning. We're visiting family at the moment and need to respect their schedule.
Thanks for the walk-through, and the good news is that I still have three good fuses. The parts house is nearby too.

Maj. Dundee, I haven't been able to get the 2-wire lead off the coolant circulating pump. I got the wire off the rubber cord end, but I haven't been able to get the cord end off the pump. Is there a trick to that, or a step I'm missing?

Take a close up photo of the connector and post it.

Your pump looks like it's been repaired. The pump has a thick rubber cushion around it and the cushion sits on a bracket.
Pull the motor with the rubber cushion off of the bracket and press the metal clip inwards and at the same time pull off the connector.
