A31 Sunroon? How To Get It To Open Fully?

[LRyder]

Hi Guys.

Tried searching, but to no avail. I have a A31 with facotory sunroof. It goes up and opens a little bit, but it wont go down and slide in. I have been told there is something I need to remove to get it to slide back in the roof? Can anyone please confirm. Or is the sunroof not able to go back into the roof.

Cheers.

With mine I have left and right toggle near the sunroof. Left to open out when closed and right to close it. I then have to release the button and push it again to open the sunroof in to the roof lining. Mine stops about half way I then have to relase the button and push it again to open it the whole way open.

Hope this helps.

They're meant to stop halfway, then wait for you to press the button again to continue going back all the way.

My 88 Ceffy doesn't do this, it just goes all the way back first go, my 89 ceffy only goes back halfway, then gets jammed.....if I work out how to fix it, I'll post it up in here.

The reason it jams is because of the motors alignment on the rail with the teeth.

When the motor reaches a certain tooth, it stops.

eg. sunroof is tilted up and you close it, it stops when the glass is flush with the roof (water sealed).

It's meant to stop again at halfway, and again at the end.

OK I fixed mine today.

It's not to do with the teeth/rail.

Inside the motor housing, the motor itself powers more than one cog.

One cog moves the rail back and forth, which is for the actual sunroof glass itself, the other cog leads to a bigger flywheel kind of thing, it's plastic, and has 3 staggered steps on it.

Tangent to that is two switches, which are activated by a larger tooth on the plastic flywheel thingy. A third switch is activated by a flat section of one of those levels.

Basically the three stoppers trigger the motor to pause.

One is for the sunroof fully tilted up,

one is if the sunroof sitting flush/sealed with the roof,

and one is for the half way.

For some reason mine was very badly out of sync, I tried to adjust the position so the stops were where they should've been but after about 4 tries I gave up, and removed the switches inside the motor housing.

It goes up, down, and all the way back, the only drawback is it doesn't stop, at all, including flush with the roof, but that's pretty easy to work around.

I spent most of today doing this, BUT I did drop the entire sunroof assembly down off the roof, which is both a pain in the ass, and time consuming. Everything got a good clean while it was down, which is a plus I guess.

If you can't remove the sunroof motor from the entire assembly, I'd highly recommend that you take the plastic trims off the sunroof glass, unbolt the sunroof glass seperately, and then drop then sunroof frame down, that way it only weighs half a ton.
