Window problem poll

[continentalgt]

Thanks for pointing me in the right direction continentalgt. So happens there is an advertised repairer on that well known site not too far away from where we live. Local dealer was prepared to put car on list of other cars awaiting availability of new regulator parts, BUT, would you believe wanted an £80 diagnostic fee!!!! In meantime, spell of dry weather, and it has started working again. I am starting to really dislike Renault brand and wife's next car, if I have anything to do with it will certainly not be another Renault

If you do have to change it try sealing the new one as I did and as explained in the first post of this thread, I did the other front controller using the same method last weekend and will get around to the rear ones when I can.
Anyone know how accessible the rear ones are, a photo with the trim removed would be much appreciated if anyone has one.
As I said previously I don't and haven't yet had a problem, I'm just endeavoring to take preventative measures.

Thanks for that. Dumb question though - what is "self amalgamating tape"? Is this what I would call "electrician's tape", or is it a special kind of tape?

No it's not electricians tape, self amalgamating tape is very stretchy enabling it to follow fairly complex contours without leaving an open edge where it overlaps itself.
It sort of welds to itself chemically and after a few days is very difficult to separate from itself but can be removed from other materials fairly easily.
A somewhat clumsy explanation, perhaps someone else here could explain it better.

Thank you - there is always something new to learn! Have sussed out where to get it from and that is a really helful tip much appreciated. Pity the auto designers don't think of these practical things when creating all their clever features which become so expensive to replace.

Hi just bought a megane 2.0 l cc all is well as long as you d,ont want to open the n/s windows front or rear ,they work ok with the roof switch or the master switch but not by the drivers switch. I have checked for power to the regulator and all appears to be ok, theres also a good earth , has anyone had this concern .

Newbie on here having bought my CC two and a half months ago.

Bought during the lovely weather we had (yes, it even get nice in Wales!) around Easter. No problems for two months, but two weeks ago, after a spell of rain, I decided to make the most of a brief ray of sunshine by putting the roof down, all well and good. However, when I got home and went to put the roof back up, the rear O/S window decided to stay down no matter which switch I tried to use! Out came the plastic sheeting and duct tape as a very temporary repair. The next morning, having stayed dry all night, I tried the window again and, lo and behold, it went back up. Four days later, again after a rainy spell, the sun makes another appearance so down with the roof, this time however, the same problematic window decided to stay in the upright position and has remained there since! When the switch is depressed there is a slight noise coming from behind the rear panel, so it seems as if the electrical connection is working, but having read many posts on here, it looks as if the regulator needs repair/replacing or just a good dry out followed by some waterproofing.

Car goes into my trusted local garage next week for a check up so I'm going to get them to look at it while it's there - if they find anything, or suggest a miracle cure, I'll repost and let the forum know.

I've found some repair kits available on ebay - if anybody has had any luck with these, please let me know.

Could be your problem, your car showing same sysmptoms as mine did I have had two used regs in it now both passenger rear both showed up same signs as yours becareful operating switch now as you will end up breaking the UPVC cable clamps on the regulator, you will not be able to repair them! glue does not work.+
Having looked at mine a couple of times now you will need around 3 hands to wrap these cables, one wraps one way, the other opposite way ,as the motor turns to wind down th ewindow the red wheel turns you see in th eebay image and plays out the cable, whilst it is playing out one cable it is pulling in the other.
What Happens When they break! well some how the cables catch up to each other or jump a grove not sure how but it ends up with a crossed cable on that red wheel, which in turn as we all know plastic and metal don't really work together the metal cable flattens the small groves in that red wheel, the groves guide the cables no guides left to "catch" the cable they wrap anywhere and end up jaming themselves on that red wheel, you keep pressing the window buttons puts one of th ecables under strain the only weak point left is that white UPVc cable clamp which shatters, window reg is rendered useless.
Been looking for this repair kit for a while but they didn't them when I wanted one so ended up with a complete used reg, it is do"able" as long as it is the cable and not the window Control box, but as said mine was the same sometimes worked some times did not, the buzzing sound you can hear could be the motor pulling against the cables. mine is bolted in place at present through the regulator mount plate to hold the glass up all cables stripped out of the motor and motor plugged back in to fool the roof.
Pick a nice day to get it out as you have to drop the roof to do it.

Really wish I lived closer as it sounds an interesting if very very frustrating fault but unfortunately I'm right down on the south coast.
I was a design and development engineer up until a few years ago fault finding and also improving the efficiency of high speed manufacturing equipment that we made in house so I'm pretty used to these kind of things, problem is it cant be easily diagnosed remotely.
I haven't got as far as removing the complete regulator yet and guess I hope I never will so cant be much help I'm afraid.

For everyone else, I'm beginning to think that with the exception of ChrisM window problems are a myth as no one appears to have had problems so how about posting how long you have had your CC without experiencing window problems.

Many thanks

High , i have the same problem with my rear window regulator, but i cant get a replacement , so i am trying a repair kit, cant get the cables in the right position though

I have my 04 Megane cc a few months now!everything was perfect with it until the other day when i wanted all the windows down! The rear passenger quaterlight went down about one inch and stayed in that position!
It wouldn't move at all until later that night when I tried it again!!
Finally it went up by itself at a very slow and unsteady rate!


This thread is a great help and from reading I can see iv the same problem!
When driving around in the car today there is a weird noise coming from under that window (like a tapping electronic noise).
How much is a new reg?
And can you buy them off eBay?

[continentalgt]

Haven't checked recently but you used to be able to get repaired ones on Ebay or send your unit off for repair, I think it was around £50 but a search will soon tell you.
You might just about still qualify for the Renault subsidised replacement as I think it applies to cars under 7 years old, I have heard people post that new controllers are on back order with Renault UK though.
My 04 plate is 7 years old this month so no good for me now if I have a problem.

[ckier08]

Well I rang the dealership today and he said my car is covered untill october!
So I'm dropping the car in to get the back passenger window motor/regulator unit replaced and Renault will pay 75% of the cost!
Should take 2hours to fix!
Thank god my car was just in the time frame seen as it's a 04 model after all.

Until today our Megane CC rear passenger window would only operate from the switch on the centre console and not from the switch on the rear panel, however today the when we put the roof back up the rear window stuck about halfway and would not work from the centre console button. We turned the car off and locked and unlocked again and decided to drive home.On the way back as I was sat as a passenger and I thought I would try the rear window switch.To my astonishment it worked!!!

I have read so much about regulators etc etc, but can't understand why the rear window switch now works.I don't want to mess about too much as everything else is fine.

Is the switch for the windows located behind the drivers door panel? Should I start here?

I would rather attempt to fix this now before it lets us down when we are out.

Thanks for any advice

[continentalgt]

Remove the switch cluster in the drivers door panel in an upward direction, prise from the rounded end of the plastic switch housing first. Looking at the switch is worth a try but It sounds typical regulator/controller to me. Don't forget that if your car is under 7 years old Renault give a 75% discount on replacing the regulator/controller, good luck.

Tip: I know its winter but open and close the roof 3 or 4 times a month just to keep it working, mechanisms don't like being inoperative for several months.

[sportsmonkey]

Thanks for the reply.

I will have a look at the switch and check it ok and not damp etc as per advice earlier in the thread.

Our megane is 05 plate so I will speak to our local renault dealer about replacing the regulator/controller.
