Sunroof Problems

[andymorris]

I now have a problem with the sunroof.
In that I can only open and close it manually from inside the boot. I am guessing at this but woud presume there is some sort of mechanism inside the roof that is the problem. When this happened the "arms" got stuck inside and would not return out. There was also a judering noise. Does this ring any bells? Would it be easy to fix? And where should I look at getting the parts?
Any advice would be greatly appreciated.
I have gained a little confidence in trying to fix it myself having succesfully replaced the starter motor[]

Source of much knowledge - http://www.clarks-garage.com/ - Garage Shop Manual, under "sunroof"
Probably the plastic 'planet' gears, have been known to strip teeth. Cheap to replace, parts often listed on ebay.

Gears are very likely, as Steve suggests. Can be a pig to install correctly though, and I would advise getting spares.
They are on e-bay but are almost always cheaper through the OPC.

Thanks guys.
Would this be a job for the professionals then?

No, providing it just the gears, its quite easy. The system is designed to strip the grears when the roof is stuck, but more often that not its the torque of the motor that causes it.

As said previously, if you look at Clarkes it's a nice step by step guide including how to re-adjust the motor.

I have to say I keep a spare set of gears as last time mine broke it rained for a week and I got wet []

From memory they are about £10 per set, the only issue you'll have is re-feeding the cable if its come out and getting on your back to do the job in the first place.
Don't forget to do the motor else you will do the same thing straight away otherwise [8|]

Good luck

I have this same EXACT problem with an S2 just now...

..with ignition on, the roof catches will retract to allow the roof to be lifted out, and will raise to lock position again. They will not raise the roof to open position though. Switching ignition on, engine running and the roof does not work at all.
However - it did work recently. It worked going up but not coming down, I had to lower it with a wrench at the motor.. so I replaced the switch (with a used item) and I now have the above problem same as you?

Would it be worthwhile looking at our switches? Try swap the sunroof switch with one of the others, see if makes any difference. I will try the same, but I wont be with my car for a few days to be able to check this out.

I fitted a brand new switch so I'm sure that's Ok
do you have 12v on terminal A and R in the fuse box?

 

[white944]

Mine does the exact opposite. Goes up and down, but cant be removed.

Same as mine, I'll be having a go at sorting it once I "have" to (fitting the Saratoga). Any repair ideas welcome?

Without trying to be patronising, but do both you guys know that the roof can only be removed with the engine off and the key in position 1. If you are trying to drop the latches with the key in any other position it will not release the roof, this is normal and noted in the user manual.

If you both knew that already and actually have a problem, welcome to the club! If not, hopefully I just helped fix your problem..

 

[Kongsodoken]

been though Clarkes guide it states that terminal A on the main relay should have 12v with the ignition on
terminal A is the Tacho input!
so anyone with electronic knowledge should I have 12v at terminal A ? I'm thinking not?

determined to solve this by Saturday

Thanks but unfortunately I knew that and have a problem!! I'm sure it's not insurmountable to sort...

Im just reading on Clarkes that to check the relay you should be getting 12V at terminal 2 of the sunroof switch plug (separate at the centre console), then check the relay for 12V at terminal R (ignition switch at position 1) and then terminals R and A (ignition switch position 2).

Not sure about the tacho as you mention?!

I'll keep digging...

 

[Kongsodoken]

Terminal A is the tachometer input Carnot figure why it should show 12v when cars not moving

 

[Kongsodoken]

Spent all day trying to find the fault and I think I'm getting somewhere
problem with these sunroofs is multiple faults can be present so it give false results
found the following problems

rear microswitches were not making full contact, had to press them quite hard against the cam to get them to close

resistance across microswitch 11 was not as in clarkes guide on removal it was perfect open/close but in situ it was showing 5 ohms. ......not sure about this one

no voltage at the console switch........relay?

no volts at terminal A On the relay socket ??? Not sure about this as this is the tachometer input I would have though this would have become live when rolling, although clarkes disagrees

first off I'm replacing the main relay, if that doesn't work then the microswitches and if all else fails then the ignition switch
