C70 Roof problems

[andrew_s46]

Hi,

I'm here again asking advice regarding my C70!

My problem this time is;

The roof on my C70 goes up and down as it should, but for some reason today it has decided to skip a few steps and no longer chimes and lowers the windows at the start and no longer chimes and raises the windows at the end.

I have checked all the fuses and the windows work from the switch on the drivers door.

Anybody got any ideas - I have a feeling this may get £££££££!

Thanks in advance

Hi,

Just a bit of an update.

I was trying the roof this morning in some hope that it may have put itself right. I have found that if i put the windows down, at the end of the roof cycle the are brought back up automatically - just no chime at the end.

Not sure if this is significant but thought it might help.

Don't get me started with roof problems..................!!

I'm afraid all you can do is get a Volvo dealer to callibrate the roof. It sounds as though it has somehow become out of "synch". There is really nothing you can do. Just think yourself lucky that the roof still goes up and down as it should. As you can probably tell, mine does not

I hope this helps.

That problem sounds familiar !, mine does the same plus the two flaps do not lock down all of the time ... Fingers crossed it does not get worse (perhaps it's lack of use ?

So have any of you had your roof problems diagnosed by Volvo. I bought my second had 03 model from a trader 4 months ago and my roof now doesn't work. I've only had it down twice since I bought it. Volvo have told me it is the roof module that is broken and it will cost around £1500 to fix including labour and vat. I only paid £6k for it anyway. Has anyone else had similar problems or just me :-(

Hi!

I have just came back to this today as my problem is still not sorted.

I did have mine checked out and was told it was the power window master switch pack that was causing the problem - I replaced it and my problem still exists - blank faces all round.

If your problem is defiantly the roof module I would just buy a tested second hand unit and fit it yourself (very easy) and then take it to volvo to be calibrated to your car.

Have you checked all the connections to the roof module? It is in the drivers rear quarter panel. You gain access via the boot (you will have to remove the boot carpet trim). Might be worth just checking to make sure no excessive moisture is there.

This is a specialised job . there are fault codes which guide to where the problem is , and regarding calibration , it doesnt alter unles a new component has been fitted and the roof has to be calibrated with the control module in the car and working the roof .
You know you ( or teh dealer ) can wind the roof up manualy ....

Well, my hood works fine, but I've already had the rear window glued back into the hood (started to separate due to the australian heat). I think it may be starting to separate again. Any suggestions? Thanks in advance.

Sorry to drag up an old thread, but my C70 does the same thing but also my roof fouls on the passenger side storage lid bump stop as it folds down. It's been suggested that the fault causing it to miss out some of the steps is also causing the roof to operate in the wrong order, which is then causing the fabric to rub. Just wondering if anyone else with the issue of the windows not lowering and the roof not chiming also noticed the roof rubbing? Or is this potentially something completely unrelated?

And does anyone know if I will cause any issues by stopping the roof while it is partially open? The manual says not to do this but I want to so I can have a closer look at the bump stop? It looks to be fairly substantial but I wondered if I might be able to bend it out of the way a bit so that it stops rubbing. Any thoughts?
