Skyroof Fixed Succesfully
Dear All,
An update on my skyroof repairs. I have finally completed all repairs and my roof is working as it should, but oh what a rollercoaster of a ride it has been! I have found out that a Renault Laguna has the same Webasto motor controlling its sunroof as the front skyroof motor on a Fiat Stilo but you have to use your original pcb, only the motors can be exchanged, but if you have a worn gear or knackered motor then it is another option for a fix. If you ever have to take everything apart then mark the two white plugs with their corresponding female plug as they are identical and can be plugged into each other which will render the roof inoperable.
After thinking I had fixed my roof, the first time I tried it, one side decided to move out of sync of the other and it snapped the main roof stop off one side. I managed to drill and pin it back together using 1.5mm sprung stainless steel wire and some very precise drilling and retaining compound. It has worked a treat. If I was unable to do this, I would not have been able to go any further as the spares just aren't available and it would have been a complete roof module out to replace it. In the end I replaced the rear blind motor complete with pcb (thanks Austin), I replaced the front motor with one from a Laguna but with my original pcb. I cleaned and checked all plugs with an electrical solvent cleaner. But the main issue that has been stressed on here many a time is the cleanliness of the moving parts of the roof. I stripped mine right back (not out of the car) and used brake cleaner and a toothbrush to remove all traces of old grease etc before using a silicone based lubricant form a spray can. It gives a really good slip but only leaves a thin layer on the surfaces so doesn't clog up. To clean the sprung steel screws, which pull the blind and blades open/closed, you need to remove each motor, then with an assistant, who is at the motor gear entry hole with a can of brake cleaner, whilst you are sliding the screw up and down by hand with the roof stripped to gain access, he is spraying up into the hole on both sides to get both screws. A tub underneath catches all the dirt being washed out. Once this has been done to all four screws, use the same method to re lubricate with the silicone spray, until it moves up and down easily by hand. If you can move it all with little effort by hand then it will move with the motor. Any resistance is a problem.
Anyway, enough for now.
