Just had a quick play now that it's light outside and the roof is completely void of life. The widows wind down just fine, but when i unlatch the roof they stay put, no signal is being sent to them to lower :-(
I looked under the fuse box and all seems to be okay except one big round socket with nothing plugged into it (this may be something for auto transmittions, mine's a manual). It's very messy under there and i could only see six fuses.
