I've got to change my passenger door lock mechanism as it doesn't always lock - is it quite easy to do this?

Once you get the door card off you can get at the mechanism, its a pretty straight forward job to change the barrel over, however it may just need lubricating.

Mine's the same, its lack iof use and lubrication. Once its being used frequently it works fine. I find I need to double check it locks on the central locking sometimes. This weather its not been on the road for 3 weeks so it will probably have started sticking again.

I've already lubricated the entire mechanism, turned the barrel manually, everything I can think of, so I bought a spare unit to go in.

So this means that all 3 connecting rods will need to be hooked up, so it was access to this that I'm curious about, seems like the whole thing is attached by 3 screws?

 

It's also possible that the pulse isn't long enough from the alarm, the drivers door actuator was replaced with a solenoid which is an immediate action unlike the original in the passenger side which has the original motor/worm drive.

ooh mine hasn't worked since I got the car, will have to try some of the above ideas! :)

It will NOT be anything to do with alarm pulse but could be the rod of the drivers door motor needing adjusted so it pulls the bar enough to trigger the cars own locking unit

Sometimes it locks fine, probably can rule out adjustment as surely it would never lock??

not really as all the actuator motor does is pull and push on the rod that goes from the interior lock/unlock button on handle to the lock mechanism. If its tight or the motors starting to seize up it might not be travelling far enough to fully operate

Door card off, free it up and lube i would say.

so how do you adjust it?

The motor has a bar rod attached to it that is clamped to the existing door lock/unlock rod and pushes and pulls when alarm is operated.

Take door panel off and check its not too tight or caught on something

cheers for the info!

Right, update time. I've tried my replacement central lock door mech on the car and fortunately decided to test it without actually fitting it. With no resistance to slow it down (rods etc) the replacement does exactly the same as the fitted unit! It moves partially to each opposite range of movement but only manages about three quarters of it's travel.

I can only think that the signal is at fault (the drivers door has a different type of solenoid).

It is also a kind of erratic movement which is kind of a similar effect as when AC power is applied to a DC appliance.

Might have to convert to the same mech as the drivers side...
