UK Citroen C3 Flair Puretech 2017 - 67 plate

[Mickiblueyez]

Im wondering if anyone could help me.

I have purhcased a new drivers side switch control, operates fron and back windows. I am having trouble getting part of it to come away from the door panel. Most of the switch lifts off from the clips but a corner bit doesnt seem to be relasing. This is the back part of the switch where the locking part is on the switch and it the part that touches the inside panel (hope that helpe)

I just need to take the old switch control out and connect the new one.
