Do you mean the heated screen, or the wiper?
Could be a fuse box issue. Do the lights all work, stop/tail/headlight etc

Sounds like the door outstation is playing up or the wires to it.

I tried the outside station from the other door, but the problem is the same, there is no movement in the left windshield and mirrors.

A friend had that problem including the door wouldn't lock off the fob and the interior light wouldn't come on when that door was opened. His issue was on the drivers door (rhd) though.tracing the cables back from the door outstation to the becm he found two cables that had nearly broke in two under the door threshold plastic cover. Repairing those two cables brought everything back to life.

The wires between the A post and the door can break where they flex.

Switchpack? If you can get a nano on it you can (try and) command the window and mirrors remotely, and if that works then most likely switchpack
