Until the night before yesterday evening my glass-slide canopy still worked perfectly. No problems. Yesterday morning I wanted to drive it back – so completely open …. just tilts down in the back, but doesn’t drive back. I can also close it again, i.e. it goes up in the back and is closed again correctly. Also I can lift it up in the back and close it again. ….. just doesn’t want to drive back. Someone’s idea of what the spirit has given up?
