307cc folding roof fault

[Pop64]

Hi,
Wondered if anyone can shed a light on a roof issue with a 307cc 2006
The sequence starts, the boot lifts then stops. The side 'paddles' do not activate and so the roof does not fold down.
Could this be a sensor or actuator issue? If so how do I go about finding it?

It is probably either a limit switch, or a broken wire in a harness. You should get diagnostics done to check the operation of all of the components. This probably needs a Diagbox tool, as I doubt that many 3rd party tools will understand the folding roof.
