Had the roof down this morning on the way to work, lovely. Thought I go for a spin at dinner time again. Car was hot from sitting in the sun. Boot lid opened, front windows went down. The rear ones didn't. So the roof stopped opening. So I closed everything back up. Then pressed the internal boot release to reset the system. Then tried to open the roof again. This time it all worked fine. It also closed back up okay. So when I finished work, I tried to put the roof down again. The rear windows didn't go down again. Doh! I reset the system & it all worked again. I'm wondering if the heat is effecting something. Anyone had a similar problem? Anyone know where the switch is that lowers the windows during the roof opening system? I know the Raise rear window switch is at the top of the front window.
