Megane CC rear window cable replacement

[continentalgt]

Hi there my near side rear window opened correctly yesterday when opening the roof, unfortunately it wouldn't return and just made a nasty noise when I pressed the button.
I stripped the complete window mechanism out today and the cables were in a tangled mess, Renault wanted £280 + VAT for a complete assembly so I ordered a window regulator repair kit consisting of cables and pulley etc from a well known auction site for under £10.
My question is has anyone here ever replaced the cables on their CC rear window mechanism, the bit I'm unsure of is how to correctly install the cables to the motor pulley.

I think I may know how the cable pulleys are connected to the motor pulley now but if anyone has any ideas I would still like to hear them.
The repair kit should be with me early next week and I will post how I get on.

Hi, I replaced mine last year.

I took photos of it with the intention of loading them up here but I can't upload pictures to this board.
Hopefully you should be able to see these links -

Note how tightly compressed the tensioning springs are. After trying for ages to get the cables on, I ended up making a clamp to hold the springs compressed -

That then allowed me to get the cable to this point, where I could then turn the pulley by hand (using thick leather gloves) and get the cable on the last bit -

Whilst I was clamping the springs and fitting cables, I did it with the motor removed and with a temporary nut and bolt holding the cable drive drum in place, so that I could move the cables more easily. You can see in the picture that I also wedged a couple of bits of plastic temporarily behind the drum to keep the cables in the tracks.

The other thing I remember is that the white plastic bits that go on the ends of the cables do fit either way up. However, due to the angle the cable pulls on one of them, it is very likely to fail (as my previous one had) if it is fitted with the cable pulling towards the slot rather than away from it. Very difficult to explain, ... sorry! Hopefully though you'll know what I mean when you see the angle of the cable in the white plastic end.

Hi Vroomvroomclonk that's really invaluable information, someone should make it a sticky, appreciate you posting will let you know how I get on.

Replaced the cables OK today, no problems at all will try to find time to write something up but pretty busy at the mo. I'm guessing a job that cost me £10 would have been £650 to £700 in a Renault garage

I'm glad it went well for you. Did you do it by compressing the springs like I did, or did you find another way of getting them on? I couldn't find any instructions anywhere before I did mine so I just made it up as I went along. I'd be very interested to hear how you did yours please if you get the time to write up a few notes.

I didn't use the springs that came with the cable kit as they were far stronger than the originals so I removed the originals from the old cables. I had to pinch in the first coil of the old spring so that they stayed in place on the new cables as they were a slightly loose fit and as you know when installing the cable the last thing you want is for the spring to move around during installation.
Having first wound the cables onto the motor drum I installed them by attaching the first cable to its mounting post (while keeping both cables slightly taught to keep them in place on the drum) then pulling the second cable end by gripping the white nylon block by hand and slipping it over the other mounting post.
It actually went much better than I thought it would, It looks like a really big job to do but it really isn't that bad assuming you have reasonable mechanical skills.
