My 2012 Octavia 1.2 has suffered a passenger door electric window failure. The motor will take the window fully down, but it will only go up a very short distance (about 75mm) before it sticks. No amount of pulling will move it. I have got to the window motor, and when removed that runs fine, so something is jamming in the cable winding system. But that is all hidden behind the inner steel door panel which is rivetted to the door. Help please???

Its probably the window regulator thats either broken some plastic clips or cable has snapped/got wrapped round something. You have to drill out rivets to replace the regulator. On my sons fabia they are large special rivets and probably the same on the octavia. Part number for fabia mk1 rivet is N  910 788 01 They are 6.4 x 10 size rivets and you will need a heavy duty rivet gun to replace them. I got a riveter similar to this from amazon. Make sure it does 6.4mm

Shop around for the rivets they vary a lot in price.

Before removing panel check if you can that the window glass hasnt come out of the bottom of the regulator. There are holes in the metal panel to gain access. Its not unknown on a frosty day for the regulator to pull away from the glass if its frozen. If one side comes out then the glass is at an angle when raising and gets jammed.

If the motor has been removed then you should be able to pretty much freely lift the window up and down by hand. If this is stuck then as Alasdair says it could be the glass has popped out the holder/s or it’s the regulator (cables).
