Decided to have a go today and wing it. Got the part out to have a look, turned out to be pretty easy. The black plastic pin is broken so the metal bracket thing that pivots (theres a little metal spring/coil thing attatched to it) has slipped out of place.
For anyone having the same problem the part is the Door Lock Actuator and the part number is 931001. Not sure if the passanger side has the same part number. My car is an ECR33 GTS25t.
Sorry for not being very technical when it comes to describing things, I'm learning as I go.
Hope this helps anyone in the future having the same problem!
