307cc roof help

[Ice203]

Can anyone help. 307cc roof won't open

The boot part opens. The arms come out and the centre roof mechanism moves but that's as far as it gets.

If u undo the bleed screw on the pump and pull the roof away from the windscreen slightly then press the button it will open.
But won't shut. Have to then raise the roof manually.

I've tested the micro switches and seem fine.

Not sure where to go from here.

Also had new pump fitted.
