thx. I have had attempted a repair and made it worse. What I found was as follows
1) The hex key to open it manually only moved the front panel up on one side, the motor then went click click click, I opened up the motor to inspect the gearing and its all fine.
2) Tested motor with it plugged in using sunroof opening and closing knob, all seemed fine.
3) Put it all back together and tried it again, motor not working at all, checked fuse's 45 & 46 neither blown
4) Blind has now also stopped working and is stuck half open
All in all very fed up. I am pretty sure its a mechanical problem with the mechanism, otherwise I dont understand why one side of the 1st panel would lift up enough to get my thumb under the glass panel on the outside of the car, when the other side has hardly tilted up. Anyone help ?
