There's a hidden side pannel that you pry open. It's located on the drivers side of the side-dash. Basically open the drivers side door and try to pry open the side of the dash console. It's right inside there with all the fuses and things.

The roof opening panel is an electronically operated panel that can be opened or closed by the roof opening panel switch. Actuating the switch in either a forward or rearward motion supplies a ground to the roof opening panel motor. The vent and soft-stop functions are controlled by the roof opening panel motor. These positions are obtained when an internal motor cam opens the roof position switch, removing the ground from the switch. The roof opening panel has an express open feature activated when the switch is pressed momentarily. The roof opening panel is closed by continuous activation of the switch until the sunroof stops movement. This function is controlled by the roof opening panel motor.

Key in OFF position.
Disconnect: Roof Opening Panel Motor C920.
Key in ON position.
NOTE: Activate accessory delay relay for this check.
Measure the voltage between roof opening panel motor C920-4, circuit 400 (LB/BK), and ground; and between roof opening panel motor C920-7, circuit 1173 (BN/OG), and ground.
Are the voltages greater than 10 volts?
GO to E7 .
REPAIR circuit 400 (LB/BK) or circuit 1173 (BN/OG). TEST the system for normal operation.
If you can't do electrical testing , there is a manual way to close it .
Roof Opening Panel Manual Operation
Remove the overhead console. For additional information, refer to Overhead Console in this section.
Insert a hex-head screwdriver in the center of the manual drive slot to depress the release pin. Rotate the screwdriver clockwise until the roof opening panel is closed.
Could be failed motor, water gets in around that area and can't escape. Begins to corrode worm gear.
Sometimes the ambient temp sensor can interfere with opening roof, like give false readings then locks roof thinking it's too hot or cold.
As an emergency, you can close roof manually (see in your manual for instructions) all the tools you need are in the cars toolkit.
Resetting the windows can sometimes fix it and check the fuses. It's not uncommon for these cars to leave showroom with some incorrect fuses.
These are electronic so the first call is the fuse box.
If not it may be the electric lock has packed up . Check your manual as there may be a manual overide cable.
If not it needs to go to a dealer as they have tools to release it.
It may also be that the roof safety mechanism hasnt engaged properly (this is to prevent the roof from being damaged when the boot has opened) . Again this can be checked by a vauxhall dealer.
P.S 9 out of 10 times its the fuse.
I am not sure what you are trying to do. But if the problem is that the roof will only open to the first stage, sun roof, and no further, the problem is the package shelf in the trunk.
If the package lid gets pushed up and is not pushed back to it's normal position, the roof will fail to open completely. If you lift the bottom of the roof at the boot, there are levers on either side to release the bottom edge of the roof, you can make certain that the package shelf is seated correctly. Once the shelf is seated, the roof will open in all of it's glory.
there is a microswitch on the right side under roof cover if roof cover not fully down boot is locked shut by microswitch you might be able to press on cover and you may here boot lock solinoid click off get some one to push boot lock if you can.t reach when you get in boot /trunk you should see small wire that travels across rear bulkhead disconnect this and trunk/boot lid will open but roof will not obviasly i,ve worked on one of these all day today and have had every thing wrong with roof you could imagine good luck
I am assuming this is a mercedes car not van as you have not stated what model or year??
If you look on your remote keyfob there is a shiny silver metal part, most owners do not know this but if you pull that it will slide out of the key remote, this is an override key in case the doors and boot will not open, if you look on the boot lock below the mercedes badge there is a small hole for this key, that will open it.
your can check is it something stuck in the lock, first operate your roof either way, if you are going to open the roof as a first action boot lid will open to backward, let boot lid fully open and stop operating the roof, ignition off and have a look if something stuck you can see, if you are going to close the roof let close the roof and before close the boot lid stop operating roof switch, otherwise faulty boot lid lock, if faulty lock but you can try by mettle key blade which is in your electronic key, first take out mettle key from electronic key then insert mettle key in to the key hole in boot lid turn fully left and open boot if not work turn fully left and push it in, is this information helped you?
This has happened to my wife's 2004 A4 Convertible 2x's. I had to read the owner's manual several times to get the job done correctly (pages in the high 70's to low 80's) ...the following is offered from memory:
The handle/tool needed to accomplish the task 'manually' is located in the fuse box on the LEFT SIDE of the dashboard. A small flat blade screwdriver will enable you to pry open the fuse cover & gain access to the handle/tool. Slight twist the tool and it comes out easily. Tool is a "T" shaped handle.
Once you have the handle/tool IN HAND, simply turn the RED part (only) on the handle until it 'locks' in an open position. Leaves a small space on the handle. Can't recall if you go clockwise or counterclockwise, but it will be evident.
Now...move both front seats forward and tilt them to gain access to rear seat. Remove the ski boot cover in middle of the rear seat and put aside. Then, 'click' the interior boot cover panel down to gain access to a 'hole' (about size of a 50 cent piece) in the top of the boot space. This hole allows you to insert (upward) the above mentioned tool into a lock/unlock mechanism in the rear deck just forward of the trunk. The tool needs to be jiggled to go 'all the way' in...you will sense that. Once in, TURN the RED part of the handle to "LOCK" the handle into the mechanism. The tool will hang down by itself.
My approach is to 'store' the roof in the open convertible position first. The front portion of the roof should be partially forward as that appears to 'release' a lever within the roof's up/down mechanism to allow you to raise the rear window portion. Thus, lift (with that friend) the rear window portion up and forward (takes some effort). The roof now has a kind of 'clamshell' appearance front & rear. The front may even flop forward but tht's OK. This step exposes the rear deck.
Twist the tool to unlock the rear deck. It should click & release and a small space appears enabling you to use hands (that friend again) under it (the deck). Lift the deck up & back until the hydraulics kick in and keep the deck vertically open.
Now you are ready to tackle the roof & rear window for storage under the rear deck cover. Get a friend, if possible to help with the lifting...remember, this is a "Manual" job! Once here, gently push back & lower the rear window portion of the roof into the open storage area simultaneously followed by the remainder of the roof itself. Watch fingers for possible pinching in the levers, etc., during this part of operation
Hopefully you now have the roof & rear window stored in the area in front of trunk and be able to lower the rear deck to almost closed position.
If so, go back to the tool and twist it to 'lock' the deck in place with roof stored.
Remove tool from the ski storage area by reversing procedure above.
Now comes the "Moment of Truth"!
With the ignition turned on and car running, use the roof switch to bring the stored roof up and all the way to the closed position. Don't forget you must keep your finger on that switch until the operation completely finishes.
Then, reverse the process to open & store the roof for a good blow dry (drive)!
refer to the owners manual, for instructions to put down roof by hand, they are not easy to follow, however, the manual key they refer to is in the fuse panel, the 1st lock to undo is in the middle section of the back seat, next the lock for the front section push down roof and lock in place. the warning light at this point will still be flashing, and the display saying roof unsecure. the bit everyone seems to forget is to go back to the middle back seat lock and relock, once that is done, display clears, and both roof and boot should work. i have no idea why this fault occured just hoping its doesn't too often. suggest also you always have engine on when operating roof. hope you find this usefull.
