Do the electric windows work? If not I suspect the cut-out switch has
activated due to an overload on the motor. Not certain where it is on an
E34, it'll be a black button similar in size to the window switch. Look
near the switches or above the driver's knees.

The window switches and the roof switch are all the same, except that the
window switches have the ability to run the windows full up or down whereas
the roof switch only has the manual setting and you have to physically hold
the switch to get the roof to move.
My point is, the switch itself can be bad and a test for this would be to
swap it with one of the window switches to see if the problem follows the
switch. I am assuming there are no physical obstructions that keep the roof
The roof switch is attached to a panel that simply snaps out, and the window
switches can be gently pried out of the shift boot. Use a small screwdriver
to lift the switches out of their respective mounting locations.
on my e34, the window and sunroof switches are not interchangeable... I did
have to replace a motor last year, it worked fine one day and the next it
was dead, then it would work halfway and die... I changed the motor and it
works like new!
