The 94-98 Saab 900 cars have numerous top issues that are known. The primary issue is the design of the convertible top Tonneau motor that is located in the right rear quarter panel behind the light. The problem with the original motors was that there was not enough strength in the housing that held the motor to support the top movement because the teeth on the gear drive would get chewed up when the motor moved out of position. The failure of the Tonneau motor causes the top to chatter about half way up or down because the teeth of the motor gears would get chipped off. Replacement of the gears or replacement of the motor is the only repair and the convertible top Control module must be programmed after the repair by someone with a Saab Tech 2 computer tool which is used to program the top potentiometer settings. If you catch this problem early enough it can be repaired by using the bracket reinforcement kit.
Check latches is also a common failure which displays on the Saab Information Display (SID) Generally, this failure is due to problems with the micro-switch located in the latches that secure the convertible top when up.
Another issue with the convertible tops has been the control module that controls the top electronically. The major problem with this is device is that it looses the ability to communicate with the Saab tech 2 tools. This problem appears to have been solved in the newest versions of the ECM.
This TSB covers the known issues with NG 900 vert tops. There are numerous others for the 9-3 tops.

Btw 125i..roof won't go down..roof starts to open then hovers between open & closed..checked luggage compartment lid tray is fully down and boot is closed..any suggestions?

Check that the hydraulic overide screw (if it has one) has not come loose to release pressure. Make sure all windows are down. Make sure boot isn't locked. Test luggage switch hasn't failed by disconnecting at the plug and get your multi meter and check for a complete circuit at the switch itself when depressed. Failing all that manually lower the roof and then refit and try then. This has worked on a peugeot 207 should also work with others

Soft top fault

This needs to go to the dealer to have the systems control module scanned for fault codes during an "active" test cycle.

My trunk will not open on my wife's 2001 slk Mercedes. It's not locked. I think something is stuck in the lock. Can you help me?

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?

My CRX roof wont go up and down with the switch on the dash, yet the boot lid goes up with the key, cheecked fuses ok, cheecked plug and control box fault LED flashed seven times and then later on flashed...

7 blinks (roof lock switch,not operated by user)
9 blinks (rear window switch not operated by user)
These codes mean user has not undone roof locks or rear window is not fully closed
Providing that is not your problem,reset roof control unit
Turn ignition off
In under bonnet fuse box remove fuse 32 7.5 amp for 20 seconds
Refit fuse and check roof operation
This clears codes and resets roof

Saab 93 convertible 1999, how do you refill hydraulic roof

To check the oil level open the boot - at the very back remove the 4 plastic clips that hold the carpet in place. Slightly to the left of the center there are 2 holes - shine a light in the bottom and look through the top one to check the level.
To add oil - fold down the seat backrest. Remove the plastic trim - held on by 4 screws and 2 pop out plastic cllips. Undo the 8 large bolts that hold the cover in place - 2 on top and 3 on front and back.Then lift up the cover from the front edge. You will then be able to get to the resevoir - you will need a funnel to poor fluid in.

Saab 9.3 Electric roof retration issue

It almost certainly will be the switches unless you have a broken wire in the loom. There is a cheap piece of kit available on the internet called an op-com that will read these cars including the roof, that will give you fault codes and live data to see exactly where the problem lies.

SAAB convertible roof wont open

I managed to sort the problem, turns out there's a shear pin. I found this pin sitting in the bag in the back (the one the roof folds into) Now i just have to replace that and hopefully it should work

My S Reg 323i electric roof.

Ive had the same problem on my car. If you open the trunk and pull away the material covering on the left hand side you will find two electric motors similar to the ones that winds the windows these motors have to be in exact sync for the whole system to work fine.

The one drives the lid and the other one drives the roof. You can engage and disengage the motors to get the roof in sync and working perfectly. Also check that when the lid closes it engages a button on the left that allowes the roof to close aver the lid after the lid has closed this button also tells the car that the roof lid is closed and it is ok to let the trunk be opened.

I also suggest that you treat the roof mechanism with some penetrating oil.
