Hi, back again and after more advice!!!
My electric sunroof has decided to only operate on one side. I have disconnected the motor and removed the glass to try and find the cause. The drivers side slides back and forwards smoothly but the passenger side is very difficult to move. I can see the wires the motor drives and wandered if either the passenger side has broken or if it could have come out of its runner.
Has anyone out there come across a similar problem or does anyone have any thoughts as what I can do???
Once again thanks for the help.
