I have a 1987 911 Cabriolet that hasn't set foot on the road for several years. I do start it up occasionally and run it up and down the drive but I cannot remember the last time I lowered the roof.

Today, I tried to lower the roof but, when I pressed the button, the driver's side tried to lift from the top of the windscreen as normal but the passenger side of the roof remained firmly connected to the top of the screen.

I pressed the button to close the roof and the driver's side (which had raised a little way) appeared to close as normal.

The roof now looks fully closed but the red "roof warning light" is on.

Any advice would be very much appreciated.
