Hi All,

I’ve tried everything I can and now turn to here for advice

I have a 2009 Skoda fabia 5 door hatchback where the electric driver window doesn’t work - only front electric windows

The situation is:

The driver button doesn’t lower the window

Driver button lowers passenger window ok

Passenger button lowers passenger fine

Window lowers and raises no problem when I insert the key in the driver door

Found some broken wires in the door bellows - which I’ve now repaired.

Believe I’ve checked fuses.

Tried replacing the dual window switch

I have an infamous double click for the central locking -incase relevant.

From this I believe that l:

The wiring is all working fine

The motor works - as window lowers with key

Switch is not the problem

Can anyone help me narrow down the issue further to get this working for the summer! 🙏

From your excellent investigations I would think the problem is almost certainly a corrosion problem that is affecting the driver's side motor module circuitboard.

The pin of the connector on the board which is the input which controls the right (driver's side) window from the switch, specifically.

I have posted lots of images of the sort of damage that can occur under the connector body, but can't remember which thread they are in.

I'll search out one or two examples and post here shortly.

Replacement or repair of motor will be only effective solution, I believe.

All of the above damage is produced by condensation in the gap between the plastic connector body (connectors have been unsoldered in all these images) and the board surface.

Thank you!

Please can you tell me where I find this board - the old ball and chain is a certified board repairer 👍

It's in the plastic part of the motor module.

I made a little video which shows safe removal of it, in this thread:

If the steel motor casing is just pulled out without the precaution shown in the video, brush damage is very likely.

On the way to removing the board, the first step is to unclip the adaptor which connects door loom plug down onto the board.

Close scrutiny of the contact forks of this that go down to the board-mounted connector will be worthwhile before delving any deeper, as there may only be corrosion on there, but I doubt it.

(Second, obvious step is to remove the 4-off Tx20 screws holding metal motor can to plastic housing).

The damage in this picture is affecting the connection I would expect yours to have damage at. (Driver's window switch input)

Thank you so much!

Plugged the car in tonight and an error would seem to confirm your suggestion also!

The window motors have no comms with any other modules (by design). They chat only between themselves.

Don't think that scan result is related to window problem.
