Hello. My name is XXXXX XXXXX I will be assisting you today.
Is this a damaged vehicle you are trying to open as it says you already have it open 3-4 inches.
sorry mark have been away, no the door opened ok and then it was shut when we come to open it again it would only open about 3 to 4 inches
I think I would be removing the door panel first before removing the wing.
Most likely is the check strap has somehow become damaged. Removing the door panel should let you confirm this and work out a way of disconnecting it.
