Unresponsive E61 Driver Window Switch

[spiezen]

Greetings everyone

There are a couple of hiccups that require fixing, but overall, I got a great deal on a beautiful E61 BMW.


The driver window switch is the first thing I need to fix if I ever want to use the drive-through 😂

Let me tell you where I am:

Even though it doesn't work, the switch does light up.
The passenger door switch raises and lowers the passenger window, while the rear two remain fixed (perhaps because the driver's switch had disabled them).
By pressing the lock/unlock button on the keychain, you may adjust the height of all four windows.
Both of the electronic folding mirrors in the vehicle are fully operational.
No LIN communication to the switch block is the reason for the 93CB error code as reported by INPA.
The driver's door card has obviously been removed at some point; the top light doesn't work, and the lock appears to be fused in the up position, even though the car locks and unlocks without a hitch.


I'm going to give this a shot:

To check whether it helps, unplug the mirrors.
To find the source of the short, follow the door's cables.

Is anything needed or am I heading in the correct direction?

A heartfelt "thank you" to everyone.

In this case, I'd bet on the swap.

Much obliged.

To double-check that, I'll also grab one from the breakers. Is complete failure a possibility with them?

Used them on a wide variety of vehicles, but only ever had one BMW.

I switched it out, and now everything is working well. Every word you said was correct. Much obliged.
