Hi guys just wanted some advice / ideas of what may be going on with the convertible roof here is an overview

1) when roof is activated all windows drop slightly and roof unlatches, and rotates and makes the micro switches that send signal to the main hydraulic pump to run but does nothing after this point.
2) connected meter to 12v supply to hydraulic pump when activated there is 12v for a split second then nothing and eventually goes into convertible roof malfunction.
3) tested hydraulic pump direct on battery works fine,
4) replaced control module still nothing
5 My Daughter said she heard a pop rear left in roof so inspected could not see anything
6) currently having to open and close with small T bar handle

hope someone can shed some lght on the situation thanks for reading
