Hello all! I'm hoping you might be able to help, So my T34 is an electric sunroof version and I'd really like to get it working again!

A previous owner had mostly dismanted the menchanism and left it all held together with twine but after a few hours and a pile of screws etc I've put it back together and it now mostly works. the motor is fine and the carriage slides forwards and backwards.

on the carriage are some small alu sprung carriers i assume these join the sunroof somehow so using some long M4s i have picked up the holes and the roof now slides in and out fine and I've sent the front corectly but the back doesnt locate properly and sits too low.

How is this meant to lock tight? whats missing?

G'day Jifop, welcome to The Registry :D

From memory, when the roof slides forwards and hits the end of it's travel, these brackets which you refer to to flip forwards to raise the rear of the roof. If these are not assembled correctly the rear of the roof will not raise up. Perhaps these are tightened so that they are solid and do not rotate?

Here is an image I found of mine before I restored it - maybe it will help?



It's hard to explain how these should be assembled, but I actually have my sunroof in pieces at the moment, so if you would like me to take any photos of anything, just give me a holler.

Mick.

BTW - IIRC - they should be loose fitting - it's the spring tension that keeps them engaged in the roof. On the picture above there is also a nut missing.

HTH

Also - from the parts manual in the library there is an exploded diagram...

thanks for the photo, I'll take another look at it tonight! the bracket does rotate quite hapily but nothing forces it to flip into position!

The other possibility is that the clutch in the gearbox is slipping too much. Normally it should be able to push the bracket causing it to flip (the roof gets to the end of it's travel but the cable keeps going - flipping the bracket). Once everything has reached it's limit there is a clutch in the gearbox that slips to stop any damage being done. If this is slipping too much maybe it does not have enough bite to flip the bracket?
