Skoda fabia MK1 windows not working

[Hardcore5150]

Hi there my Skoda fabia MK1 2005 hasn't had working electronic windows for months, I've replaced the drivers motor, checked wiring between a frame and door, replaced window switch, windows work if I unlock the car with the key in the door (for about 10-20mins then stop) but do not work if I unlock with the buttons, haven't a clue anymore what could be causing it. Any help appreciated.

Are you saying the windows don't work with the ignition on and the car running?

The windows don't work at all unless I reset power to them or open the car with the key physically in the door, rather than the buttons to unlock, this makes them work for about 10mins then they stop working again and won't work at all until I reset power to them or lock/unlock the car from the outside door barrel again, it's an odd one.

Up to about 20 or so years ago, when you operated a switch in a car, that switch was either connected to what it operates directly, or via a simple relay. That switch would control what it was supposed to, and usually have no control whatsoever of anything else in the car.
Since that time, the electrical items in a car have been increasingly controlled by a computer, known as something like a 'body control module', and all the switches do is to send a request to the computer. This allows all kinds of interactions between different systems, which we have come to expect, but unfortunately means that when thing go wrong, the fault finding procedures that the OP used, don't tend to work anymore.

in other words, might be advisable to get the system diagnostics at work. might find a fault code in the ECUto help trace the fault.

Sorry, still not clear. What did you mean by "reset power to them"

On the cars I've had, the windows don't work after you use the remote to unlock the car. You have to switch the ignition on and then they work. But if you switch the ignition off again straight away, you get a period of grace, 5 or 10 mins, when the windows work, and after that they stop working. At least that's how some cars are designed.

So much of what you describe seems normal behaviour to me. Obviously if they don't work while you're driving along there's a problem!

I agree with you on that it's overcomplicated for such a simple action, give me a wind up window any day haha.

Seems to be a common problem! Various suggestions if you haven't seen them already

Both front electric windows stopped working

I have a Skoda fabia 2007 and both my electric windows have suddenly stopped working. I have checked all fuses l. All fine. I have checked continuity on all wires to switches and motors. All fine. Even done some soldering on the switches to rule them out of the problem. Really starting to grind m...

Yes seems that way unfortunately, thanks for the link I've already read literally any and all forums etc for the issue that's why I've now posted myself as they didn't get me anywhere checked everything I've been told to check and I'm an AC engineer by trade so used my own thought process and stuff to check certain things, still no joy apart from getting it to work for 10mins which is odd as hell.

Reading that thread gives me a complete lack of confidence in Skoda electrical systems!
