Central Locking Problem

[stew-b]

had my 300 just over a week now and the only problem i have with it is the passenger front door central locking-it doesnt work..

the only way i can lock or unlock the door is manually with the key,even the lock switches on the doors dont lock it.

i removed the door card and both control cables are in place,i tried to get the lock out to inspect the cable plug but it is very tricky to get out due to the window regulator..on my old soarer and celica i had similar issues that was down to corrosion on the connection plug on the lock..

the indicators only flash if i have manually locked the door so the car knows its not locked if i havent done so...so some of the sytem knows what its doing!

any ideas?

thanks

If it is similar to the LS central locking it may be the motor in the lock assembly,I had the same problem with the front passenger door and replaced the motor from a donor unit,bit of stripping down of both the door and lock assy and a little soldering but cheap!

I've done a similar motor swap on a door actuator on another car I had, the motors are available from Maplins if I remember correctly, so as long as the pinion gear can be swapped over, it is another way to repair a faulty unit.
