Ok so the roof on my slk doesn't work, and the shops cannot fix it, the problem with it is, that the roof or the trunk lid won't lift or move at all, does anybody know what may be the problem?

Any noises or any further detail? - lights etc? - is it in the open or closed position?

They've checked the 40 amp fuse under the hood?- position is listed on the lid

SLK-230 ROOF OPERATION

:)This is how, I believe, the roof top opening for a 1998 SLK-230 works. Remember this all computer N10-3 controlled. Moving control switch S84 rearward causes the computer to roll down the windows, powers solenoids
A7/5y1 and A7/5y2 in sequence (hereafter identified as Y1 and Y2), and turns on the hydraulic pump by its relay A5/k1. Fluid pressure from the hydraulic pump is applied by direct lines from the hydraulic pump to:
1, Solenoids Y1 and Y2
2. The closed side of the trunk actuators (rod retracted).
3. The lock side of the windshield actuator (rod retracted).
Solenoid Y2 powered provides a hydraulic fluid path from the pump through solenoid Y2 to the windshield and trunk actuators to operate. Hydraulic return fluid flows from these actuators by direct lines back to the reservoir enabling the windshield and trunk actuators to operate to the open position. Switch S69/9 (contacts open) senses when the trunk is fully open. At the same time fluid operates the windshield lock actuator (rod extends). The windshield lock actuator rod extending rotates the windshield lock hooks mechanism to unlock the windshield and
S69/2 and S69/3 contacts close to ground. Computer N10-3 senses these grounds as a locks are open signal. Rotation of the same mechanism causes by cables connected to the lock hooks assembly, to unlock mechanical latches that hold the top from lifting off the windshield. These mechanical latches are located on the left and right "C" pillars of the roof. If the computer N10-3 senses the windshield is unlocked, sensed byS69/2,S69/3 contacts closed, the trunk is fully opened (sensed by S69/9 contacts open), the trunk partition cover is extended in place sensed by S69/10 contacts closed, and the trunk key switch is in the correct position sensed by S69/12 - solenoid Y2 still powered directs fluid to both roof actuators (rods to retract) to raise the roof off the windshield. Solenoid Y1 is now de-powered and supplies a return fluid line for the roof actuators to operate. Separation of the roof from the windshield is sensed by S69/1 closing its micro switch to ground. Roof continues into trunk and when fully in place will contact mechanical locks to hold the roof down and this is sensed by switch S69/11 opening its contacts. Computer N10-3 sensing S69/11 being open de-powers solenoid Y2 which supplies a return fluid for the trunk and windshield actuators to lock the windshield and close the trunk. Hydraulic pump when running always has pressure to these two actuators by direct lines and can now operate. The trunk closes and locks, sensed by S69/9 switches closing. Both Y1 and Y2 are now un-powered. The windows roll up and the hydraulic pump is un-powered by releasing the switch S84 to neutral.
If anyone sees a mistake in the above, feel free to correct it .
