Volante Mechanism

[old phart]

2009 DB9 Volante. American passenger side latching mechanism for the rear lid isnt working properly. Making a ratcheting sound and doesn't complete the movement to latch down the rear deck portion. Sounds like a gear may have stripped a bit. I know I've only got one or two more cycles before it's shot so I hesitant to cycle it without having a plan for repair/replacement.
Any assistance out there? It's right at the very end of either the raised or lowered portion of it.
