The sunroof on my 75 has decided to not slide back all of a sudden, just when the painters need to remove the seal to paint the roof. I played around with it today for them and found a broken cable tie caught up in one of the little spring loaded cams that are pushed down as the roof starts to slide back but it still didn't work. God knows how that tie got in there! I took the motor out and it is fine and so is the switch. The roof raises OK but won't slide back. I assume the motor has some sort of overload protection that prevents it from working when a certain amount of resistance is encountered because it doesn't do anything. There is no sound of straining or other noises, but as i said it spins beautifully when you take it off. It is a pain in the arse because now I will get the car back and won't be able to use it till I get the roof working and put a new seal on it. It is winter here too! The guy is going to pull the seal off but it will be damaged because the roof can't be slid back to remove the seal from the front.

Has anyone an idea what the problem might be and can someone please post a step by step on how to remove the whole sunroof for repair?
I wouldn't bother with one if I had a choice. They are useless in hot countries like ours because you are liable to get sunburned or heat stroke. I don't care if I have to disconnect the switch and not use the thing, but I have to get it working to put a new seal on or at least dismantle it to do that. Any help will be greatly appreciated.

Try this. With the motor in place, use a large flat-blade screwdriver to turn the drive mechanism to open the sunroof toward the rear until it binds. Then push down from the outside on the rear of the panel. It should drop down and then function normally.

I have a nice write up on how to dismantle the Sunroof completely and fix the common problems. However I believe the site I originally got it from has since disappeared.

Give me an hour and I'll try and scan it in and post it up :)

Edit: Unfortunately it seems I'm missing a page, so no real help to you.

ROCK ON

I have the car back from the painters at last and need to fix the sunroof now. I got a new seal from The Spare Place here in Adelaide. They are the same as the 164, so that is not a problem. I have had a look at the thing and so far haven't managed to determine why it won't roll back. It still lifts up and down and the motor spins fine when you take it out, but when you try and roll the roof back the motor makes a click like a relay and doesn't move. I need to get the remains of the old seal out from the front edge and put the new one on before I can use the car (it being Winter at present). I notice that there are two 6 or 7mm bolts holding the top panel onto the raising mechanism. If I undo these will the panel come off or at least move enough for me to be able to replace the seal? I am not fussed as to whether I can get the whole thing functioning properly or not as long as it seals. The other thing is that at the moment the top panel sits too low at the back after you lower it and I haven't figured out why yet. It was fine before the car went to the painters except that it didn't always close fully without pushing the flap at the front down. I am sure it wasn't a result of anything the painters did because they called me as soon as they tried it.

Any advice is needed urgently and greatly appreciated. I want to drive my car! It is the only five seater we have registered at the moment and we have an Italian exchange student with us who we want to take out.

All of ther ones I have seen (including mine) have broken runners. They are cheapo pot metal and if there is any bind they will snap. I have a brand new suroof assembly, just never got the gumption to swap it.

I too would like a step-by-step guide to swapping as well if anybody has one.

The brittle pot metal pieces are part of the cables, which can be replaced without too much trouble if you can find a good set. I think it is a GM sunroof assembly so it may have parts in common with US or European GM cars. I used to have a parts list kicking around with the Alfa part number on it so they used to be available through the dealers.

I don't want to hijack oz's thread, but I emailed a sunroof specialist yesterday asking if he might have cables for the Milano and he seems pretty confident he can help, but needs a picture. My cables have bits missing (pot metal stuff) so pictures of mine won't be much help. Anyone care to take some snaps of a good cable assembly or the brackets that break?
