Rear drivers side door locking issues
« on: June 02, 2014, 04:31:02 PM »
Hi,
My rear passenger driver door  will not lock /unlock using the key fob.All other doors lock/unlock. When I lock the car from inside using the driver lock handle ,all door operator correctly apart from the passenger rear door.
I can still lock/unlock the rear passenger door using the lock handle inside.Which is a god send as I can make the car secure.But it is apain when getting into car as you got to go inside to unlock iy.
I have taken the door panel off and there are no wires snapped .I have also checked the wiring in the panels and joins on door and cannot see any probs.Any tips please welcome.
Thanks

Since the rear two doors are sent a common set of signals from the BCM, we know thats working. All that happens after this spur is that the cables pass into the door and on to the lock motor. I would say with almost 100% certainty that you've missed one or more broken wires. You don't need to remove the door card to see them as they break within the grommet between the door and cabin.

If you are 100% they are in-tact then its possible they have broken internally yet look ok externally - you can use a multimeter in continuity mode to test this. Remove the B pillar lower cover and find the reverse side of the door connector.

Then from the lock's connector check for low resistance (Sub 1Ohm, the closer to 0 the better)
Pin 1 (Yellow) to pin 4 (Yellow) of the door connector's rear side
Pin 2 (Yellow/Blue) to pin 5 (Yellow/Black) of the door connector's rear side
Pin 3 (Brown) is at chassis ground
Pin 4 isn't connected
Pin 5 (Green/Blue) to pin 2 (Green/Black) of the door connector's rear side
Pin 6 (Green/Blue) to pin 3 (Green/Yellow) of the door connector's rear side

Hi I have had same issue on mine with both rear doors on separate occasions the first was the old common problem broken wires in door loom the second I after testing everything ended up replacing the latch which came complete with the central locking bit got it off eBay for 15. And worked straight away and no probs since, hope this helps

Be careful of using the old fashioned way, modern cars have many more ECU's that won't thank you if you ram 9V up a signal wire!
The wiring isn't identified in the schematic so you would need to measure the voltages at the plug to decipher what wires doing what if you want to test the solenoids operation...
