Hello all, I’ve just purchased myself a 2006 w164 ml320. I’m baffled but I don’t seem to have any power at all in the cigarette socket nor any other outlet in the car.
I’ve checked all the relevant fuses in the boot fuse panel but all were ok and replaced them for good measures but still nothing.... any ideas as i’m stumped

With the key on, check both contacts at fuses 44, 45 & 46 in the cargo area fuse box with a test light or DVOM .

The rear wiper does work however it stops half way on songle wipe and then works fine when used with a spray . but bottomed that out to a motor issue. So I guess power is getting to this

Before I post instructions, have you checked both contacts at fuses 44, 45 & 46, with a test light?

Locate the Rear SAM unit in the cargo area and at conn. "G", find wire #21 BLUE/WHITE.

With the eng. running, probe the contact at the wire and see if the test light illuminates.

Ignore my last the sam just seems to be located a different way around!
Mom tested slot 21 blue and white wire and no power here too. I tested other wires within the same connector box and they had power

Did you just buy this truck, if not, you must have done something to one of the interior sockets to cause this problem?
