Ok, I know its difficult but you can actuate the mechanism from inside the vehicle. Remove the whole actuator and take it to someone with a compressor and blow it out. Mine had half the Simpson desert in it....I could not believe how much crud and dust was inside it. I sprayed mine with a Loctite product, cant recall its name, but its specially for locks, then go and spray your doorlocks, and your ignition lock and your house locks and all the other locks you have....its that good. Reassemble and for the next couple of weeks you wont believe how easy your rear door closes and opens.If you are like me and realise thats its not a very scary operation to do same to your other door locks go ahead and service the others the same. You may need to goto supercheap and buy some of those fasteners that you break as you remove the door linings. I also laid double sided tape and better plastic on the doors when I reassembled them.
