Hello this is my first post on FF! I've spent ages now browing this forum for solutions to my skyroof problem hoping that someone would have the same problem as me, but it doesn't appear so.

I have a 3dr Stilo and the skyroof is currently stuck open, the first glass slat is fully open, and the rear slat isn't fully in place yet. I have tried the reset procedure with no luck, and tried operating the roof with my key remote.

I have tried to diagnose the problem, so far this is what i can assess...
1. The initialisation producedure does produce a noise from the front motor, almost like the cogs are slipping, so i know the front motor is working and the switch isn't dead.

2. The blind is stuck open and the blind switches don't work at all.

3. The skyroof panels appear every so slightly twisted, it seems the panels twisted when the roof was being closed and now it is stuck with moderate force not being able to budge the panels at all.

4. The manual winder procedure doesn't work either.

I was wandering if anyone knows where i can get a schematic of the roof so i can see some way of fixing it/dismantling part of it. I am not overly bothered about getting it functioning at the moment, i just want it shut and water tight. Tomorrow i will undo the 3 torx screws holding in the front motor and try and see if the telescopic cable is broken, and if there is any way to clean the runners in the position it has seized/stuck in.

I'll also upload a picture of my roof tomorrow. If anyone could offer any help in this matter i'd be quite simple over the moon As of this moment i can only drive her in the dry and have to put a car cover on her every night!

Any questions regarding the roof i can answer straight away. Also, if anyone knows of step by step instructions to remove the roof that would be amazing since i can source another 3dr roof should no other solution be available.

Thanks.

just a thought but will it open? if it will give it a good lube and see if you can get it shut sounds like its sticking on one side?

Thanks for your reply.
I am worried that either one of the cables has snapped or that its come out of the runner on one side somehow.
I'll trying spraying some lubricant on the mechanisms and see if the manual winder will work either way, but at the moment its seized.

If it does open i'll try the advice of cleaning the runners and using the reset prodecure. I am not sure whether the rear motor works though since i can't hear that one. Some people say its just for the blind but other say its used with the other front motor to move the glass.

I'll certainly try lubricating it tomorrow in the daylight and see what the result is.

If anyone knows how to access the rear motor without puling down all of the headlining, there must be a way of just pulling down a small area to see if it works?

Thanks again

Rear motor is for blind only (which presumably still works).

You might as well drop the lining, remove the front motor and attempt to free the mechanism and just pray it's not broken

Preventative maintenance is critical for these sky-roofs.

Thanks a lot i have spent the whole day looking at the roof today. I took down the headlining and inspected both motors. I used my multimeter to test the motors and eventually removed the whole thing, and its not sitting in my hallway!!

My rear motor isn't working, but the motor itself turns when there is power to it, i assume the pcb is knackered so i'll have to buy a whole new motor now!!

I found the problem as soon as i got the roof off. The problem was that the roof had go jammed sometime and then the manual winding led to the cable getting bunched up. Now i cannot use the old cables since they were bent beyond repair. I now have the hard task of trying to find two new cables, and i can't for the life of me figure out how to undo the cable so i can take it out.

I know that the cable pushes and pulles the mechanism open and shut but i can't see, nor can i access the end of the cable (bowden cable). Fiat can't help with schematics, nor will Webasto should anyone have the same problem.

If anyone knows how i can find the part number of those cables that would be brilliant, or knows of a schematic, or how the cable attatches that would be great. I'll keep the post updated so everyone can benefit from this job.

If anyone needs advice on your sunroof i've got it all apart and have taken various photographs along the way.

Hi Austin09 sounds like a good idea (posting pics and stuff) you can put them in the guides section (dark blue bar near top of page) as the skyroof is a commonish problem :slayer:

The operating cables are not listed seperately on ePER. Looks as though you have to buy the complete frame at £1376 +VAT

The motors are listed seperately at about £250 +VAT.

Secondhand motors are often listed on eBay.

Dave.

most expensive bits of wire I ever heard of, post a pic of the bowden cable includind Diameter and end fitting as I use them at work, and may be talking myself into a job for " saturday morning"

Thanks guys its really helpful getting another opinion. I'll be taking more photos as i go and probably write a guide when i know everything there is to know about them!

You mentioned these parts are listed online somewhere? Is there anywhere i can see a diagram of it? I wanted to check the mechanism since i can't see in the runners to see how the bowden cable actually moves the glass of the skyroof. I certainly won't be spending that much money since my car is only worth a little more than that
I can get the roof watertight but after spending a whole day working on it i'd love to have it working!

Dave, that would be great if you could offer any help. I'll measure the cable tomorrow when i get it laid out flat. I am not sure how long it is yet though since as i say i don't know how it attactches to the mechanism, and hence how to remove it. I'll send some pictures of the cable as well and post online. Unfortunately i forgot to take one of it all mangled up but you can clearly tell where it has bent so beware anyone wanting to use the manual procedure you don't turn it too much!!

At the moment i have my car in pieces and a giant hole in the roof I can't wait to get this working!!

Thanks again everyone! Any extra advice will be very much appreciated!

ePER is the Fiat electronic parts catalogue, the diagrams are very vague and only intended for locating part numbers. Here's the diagrams anyway. Only the numbered items are available seperately. Most of the parts are obvious what they are except item 3 on the last page which is the electrical wiring loom for the roof.

Dave.

Thanks that really great! Can you get descriptions and part numbers for that? Also how would i access that should anything else go wrong?

I THINK... i need number 10 on the first page, that seems to be the cable that operates the glass panels. It could be 9, 10 or 11 that i need on the first page, maybe all. I'll have to phone back Fiat again tomorrow since they weren't at all helpful the first time, but this should help!!

Do you know how to remove the glass panels? My plan of action tomorrow is to try and force back the glass panels as far as i can go (since the mangled cable isn't allowing free movement at the moment) and try and take off the front pane and have a look at the end of the cable and see how to remove it.

Once i am somehow able to get a new cable for both sides i'd need to make sure its put back exactly the same into the mechanism or the motor may end up turning and pulling the cable out or something like that. Since you pull the cable out to close the roof i assume that logically it should be removed with the roof fully shut.

I'll pop some photos on here tomorrow afternoon anyway and hopefully it'll come clearer!

Items 8 & 9 on the first diagram are drain tubes to drain water from the roof channel.

Items 11 are one way valves for the drain tubes where it exits under the car.

Item 10 is just a cable tie to hold the drain tube in place.

As I said in post #7, the operating cables are not available seperately.

Dave.

Thanks. Now you have said that it seems obvious its the drain channel, maybe it was wishful thinking. Ok i'll have to try and source two new cables, but first, somehow i'll have to get the old ones off and see how to reattatch them...

I've e-mailed you some info. from the Stilo manual, it's too big to post on the forum. There's some info. on removing and refitting the roof and the glass panels. It also explains the rather complicated looking adjustment proceedure for when you've refitted the roof.

There is some other text that I've read through and there's no mention anywhere of the operating cables as a seperate item, or removing/refitting them.

Dave.

Thats great thanks i got the manual. It shows me how to remove each individual glass panel which i think i'll do next to allow free movement of the mechanism and try and find out what originally caused the problem.

The only part i don't understand is that "clock spring" that is used to push to the mechanism since i can't see that. Also i can't get at the bowden cable since its an integral part of the runner, although while at "closed" position with the panels removed i should be able to access the end of the cable and go from there.

I'll upload photos etc. when i get too tired/frustrated from working on this today!

The manuals are translated from Italian so there's often confusion with translated technical terms. I've never seen the internals of the roof mechanism but at a guess, the "clock spring" in this case may be a drum, attached to the motor spindle, with an external spiral for the cable to grip into (a similar mechanism is used for some side window regulators).

Dave.

Hi guys i've just finished my second day of my sunroof job and i've pretty much dismantled the whole thing now!
Having finally figured out why the whole mechanism has jammed and reaching the end of the bowden cable i am in a position to try and actually fix the thing!

I have taken a lod of pictures for anyone attempting a similar job, however for now i'm just going to upload the problem relating to this thread.
I need one, preferably two new cables, however the problem is that the end fitments are not removable since these are an integral part of the mechanism which acts as a runner to push the glass panels open.

If i can somehow get new cables, and attach them to the mechanism AND remember how this all goes back together i'll have my baby back together and working

Here are some pics:
The first show the roof when first removed with the cables and wiring still in place. As you can see the motor is used to push the screw thread of the bowden cable which creates the pushing/pulling motion to open and close the mechanism.









The next set of pictures show the roof with the cables just attached to each runner.





Then i have taken off two glass panels and managed to remove the cables completely.





The final picture shows my latest problem, trying to remove the cable from the runner itself (this part at the end of the cable slots in the runner and basically controls the whole mechanism).



Also any advice about how to get these bowden cables since i should get two new ones while its all apart.

Can't offer any advice but excellent repair attempt all the same

Haha thanks its been a bit of a job and its not done yet! I still have the "i can fix it" mentality, but not for much longer!
