I've recently posted a thread relating to my Octavia doors which lock themselves. A user was quick to point me to the 4th door microswitch, as my 'lights on' alarm also fails to sound when the doors are opened with the lights on.

Another annoying electronic fault I have is to do with the drivers window. If I pull over with my window open, and then flick up the window switch to close it, the window partly closes then stops by itself and opens again! I have to wait until the window is fully open before holding the switch up to fully close it.

Does anyone know if these electronic issues are related?

Incidentally, I have found guides on this forum on how to change the 4th microswitch, but it all looks a bit complicated for me. Looks like it might take an engineer a good while to do the job. Wondering if I'd be advised to sell and get a newer model before the electrical problems start to mount up....

Your '51 plate should be good for a few more years!

Might be worth checking for water ingress into the plug for the convenience unit / window motor assembly in the drivers door. The pins have a habit of corroding if they get wet.

Does auto open/close work as expected when your driving / engine running? You can enable auto open/close by holding the close switch in the close position for 5 seconds after the window has closed (iirc) - think that is covered in the owners manual though.

Bizarrely, this has never happened when I have closed the window whilst driving, nor has it happened to any other window. Only ever happens when I'm stationary with engine running and on the driver's window.

Weird!

I have tried this again, just to convince myself I'm not going mad, but amazingly it is true:

Help!

I am thinking lack of power to the window motor. Got to be worth checking the earthing points on the door/motor/loom near the door.

Like sunroofs, the window have a protection against trapped fingers that is also triggered by friction in the mechanism. Perhaps when driving there is enough joggling to help it past the friction?

Another test for high friction is to place your hand on the glass and help push the glass up when raising it electrically and when the car is stationary. If it works, then look for high friction such as caused by cracked rubber and lichen in the rails,

Try squirting WD40 or similar onto the slide rails for the glass

Not sure if I'm imagining this, but if I listen carefully to the engine when I try to close the window there seems to be a slight drop in engine pitch (as if the engine is about to stall) right at the same that the closing window stops before re-opening.

Don't know enough about this - but does that sound like something? Or am I clutching at straws? :-)

The electric window motors draw a fair amount of power. I have noticed that if your driving at night with your headlights on, and close the window, and keep your finger on the button then that will cause the lights to dim once the window has reached maximum travel. I can't say I have noticed a change in engine tone, might experiment later!

It's more like an engine 'shudder'. Might it be the 'shudder' of the engine (and brief drop in engine power) that causes this electric window fault? Or do you thnk that it's the other way around? :wonder:

I'll keep experimenting. Each time i get home from work just now, I'm cycling the window up and down to see if I can spot a pattern. Call it building up empirical evidence

I would suspect the window would be including the shudder.
