Also worth cleaning the door contacts the lower two recessed pins operate the door lock the upper three handle the auto closing etc. Use a plastic kitchen cleaner or a fine emery cloth to clean both sets of contacts - but be aware they are live at all times so don't use wire wool or metal or you will pop the fuse!

Thanks for the advice folks.

I had managed to prove that a pulse of voltage was getting past the door contacts, so I'm pretty confident that the motor was at fault. Especially after completely removing the motor from the mechanism, but still having it connected electrically and locking the driver's door. The motor gave a tiny puff of smoke as it spun its last feeble attempt.

I've got a replacement Mabuchi motor on the way from China that looks almost identical, apart from a very slight difference in the positioning of the contacts which I'm hoping won't interfere too much with how it fits in the housing. Might need a bit of a custom solder and wiring job to integrate it properly. I'm also assuming that it runs at the same RPM as the original - the model has been touted as a good replacement for other C/L solenoids for various makes and models of cars so it looks like there's a bit of a standard. It's certainly worth a punt anyway. Once it arrives I'll update. If it works it will definitely be worth the £1.65.

Success! My ebay motor worked a treat. I've already bought another 5 for future use, I'm going to assume that the Passenger door and Boot use the same one so it made sense to have a few spares. This is the one I got, but there are plenty of them around.

Dimensions-wise it's a direct replacement or the one in our Bongo, but the terminals are different. They're buried inside the plastic housing and I think you're supposed to use some kind of push-in connection. I had to chop away at the plastic and solder on some wires to extend to the existing wiring. It's messy but it works:

It was a bit of a pain to get the brass screw off the shaft of the old motor. I managed that by jamming it in a vice and heating the screw with a soldering iron, while pulling it with a pair of pliers. it came off eventually. Simple enough to hammer it on to the new motor.

All fitted back inside the casing, with a generous helping of white grease. One thing to note about these motors is that the terminals are reversed compared to the existing ones. The yellow wire originally went to the furthest terminal. I had to find this out the hard way, and bring it back inside to re-solder.

Once it's all back where it should be it works great, so I'm guessing it spins at the same rate as the old one as it hasn't over-rotated and broken. Happy days! Being tight has paid off in this case. :lol:
