Well after removing the old roof, swapping motors and attaching hydralic lines I put the new roof on, filled the system with hydralic fluid and bled it and that's where I encountered my issue of the roof not retracting, it unlatched but didn't go down, after alot of head scratching, cussing and searching the Internet I was completely stumped! Took it to martin and in a few minutes he found the issue, I had attached the 2 electrical connectors on the back of the motor the wrong way round!!! So when pressing the roof button it would unlatch but then try to do itself back up lol, rookie mistake lol
