Passat B5: Driver Window Not Working (1999)

Hi,

The window lifter on my driver's side door is malfunctioning: When I press it briefly, it either goes all the way up or all the way down, and sometimes the opposite happens.

Is it possible to pair it somehow?

Also, the loose window rattles when the door is closed. Does anyone have an installation/removal guide for the door module?

Thank you very much for your help!!!

Hello, the window switch on the driver's side sometimes malfunctions. It's a known issue with the Passat/Golf.

A new switch block costs approximately 35 €.

If you're skilled, you can often repair it yourself (at VW, they just replace everything!).

Beneath the rubber mat, there is a circuit board with contact areas. These areas are connected by conductive sections on the underside of the rubber. (Those who have ever opened a remote control (TV, Hi-Fi, video, etc.) will know what I mean.)
And this conductive layer on the rubber is no longer conducting properly.
The error code in my car's system indicated: "Driver's side switch, implausible signal, intermittent."

I got some "graphite spray" and applied it to the damaged areas in MULTIPLE LAYERS. And I made sure to let it dry completely in between each layer!

That allows these areas to drain again, and everything is okay!
It also works with remote controls (something I've been doing for years).

Nowadays, there are also repair kits available for remote controls. It probably wouldn't be very different from my method. I haven't tried it yet, though.

It's also possible that the brackets holding the window glass in the door's electric window mechanism (eFH module) are broken. This was quite common in the Golf 4, but now there are reinforced brackets available. I had similar symptoms on the driver's side.
