2000 CLK320 Convertible Power Windows
some window operations were wired to the power roof module in the trunk.
That was a mess and I found some bad wires... a quick repair/clean up an
all windows work properly!

Hello, new to the forum...
My younger brother passed March 2025 and I am taking over his project car.
It's been garaged since 2019 but it runs and drives. I am trying to get it ready
for PA State Inspection.
The front and rear power windows do not work. I checked the fuses under the hood,
all 4 ok. New battery installed and maintained charge March 2026. I have a couple
spare window switches but they don't help. I have the driver door panel off now,
not sure where to go from here. The power seats work fine, as do the power mirrors.
A/C, lights, radio, signals, flashers, wiper all work.
There is power to the connector to the driver's side window motor, not sure yet
about the connectors to the switches on the console. The mirror switch on the console
does have power and it works. Can someone point me in the right direction please...
I'll appreciate any advice.
