Stuck Tailgate

[elmo]

Hey guys,

I did a quick search but really can't seem to find anything. Despite the rear window working fine, and winding down with the key and back up fully, the rear tailgate somehow has just stopped working.... The pin to release it (the lock) just wont budge so I cant drop the tailgate.

Any ideas?

The window isn't fully down.
