Hi I have a mk1 fabia vrs 2007. The front windows have stopped working, replaced the motors and control module on drivers side. Brand new parts, with the door card and module off and loose the windows work. As soon as you put it all back together they stop working. At a loss. Can anyone help? 

Check fuse 11. 

 

Just checked, it’s intact.

Would you suggest changing the loom? Everything else has been tried I think…

What part number is the motor module you replaced with brand new? 

Do you have a multimeter?

They sent the wrong part out twice I know that, it was done by Dan at PD parts. I don’t have a multimeter no.

Look for whatever info came with the one you have now.

It should be 6Y2959802.

There are relatively few wires to check to prove that the loom does/doesn't have any broken wires relevant to the windows, so borrowing a meter might be wise. 

Measuring voltages is often more convincing than just visually inspecting wires.

Is the door card currently on or off?

I’ll get it to someone with a multimeter get them to have a look, no it’s all back together now. Gave up with it again in the end. 

I'll pop up a circuit diagram later, with what to measure, and where.

Don't suppose you took any photos of it before refitting door card?

That would be wicked thank you. I didn’t no, it’s going back down Monday so hopefully between you and Dan can get to the bottom of this issue. Windows seem to be a common fault on these

Here you go. Measure each 12V feed relative to the thick brown wire, obviously with ignition switched on (or engine running) for the black/blue ignition switched one on the 6-way connector. J386 is driver's side window motor module, the rectangle below it is the switchpack. Fuses at the top.

 

Ideally you'd check resistance of the wire that goes all the way from pin 3 of each 8-way window motor connector (driver's to passenger's), via the A-pillar connections, to ensure that it makes it, uninterrupted, all the way. That's the LIN data connection between the two modules (and nowhere else). It's a grey/white, thin wire.

 

If all that checks out, I'd be looking to check, again, that you've been supplied with the correct part number, and that it is indeed new. Check date code on label.
