First day of sunshine- roof refused to fold down; but the windows on same switch, in centre console, working. As I checked the fuse, roof worked. Fuse fine. Came to put hood up again- not working again. Turned ignition off and in again, flicked switch a couple of times- roof went down. Does it sound like a break in wiring from switch to power and why are the electric windows, on same switch working? I can't find a Haynes manual for my model; latest is 2009, or any wiring diagrams. Any help appreciated. ?
