Doors locks,stopped locking/unlocking one by one. Cannot lock or unlock any doors from key fob or inside panel except for the drivers side. They started doing this one door at a time.

Can hear some noises when using the key fob, like it's trying to unlock, but does nothing.

Pull drivers rear door panel off
1. Remove door lock solenoid and plug it into another door to see if it works
2. If you can reach inside the door to the final mechanism that everything pushes on, push it yourself to see if it works
3. Also look on side of door for possible child saftey lock switch

Central locking


That is correct. The door unlocks when you pull the inside handle. All in the interests of safety. On my car, a single press on the fob opens the driver door only, two presses opens all the doors.

General advise:The lock is not ok.The same wires that lock the doors,unlock it.Before removing the lock:ceck fuses,door wiring link (near the door hinges)U may have to figure out the link covered in removabile rubber(it has a lock pin and must pull down in some cars rotate)U can clean it by air gun and contact cleaner.Rare:The door unlock pin (small plastic knob that u unlock manually from inside)has the rod dirty/stucked/twisted,ceck it to move loose.Also spray chain lube and wd40 anywhere in the lock u gain acces (the key hole,from sides,from the pin lock).U can see if it is stucked if the unlock knob has the intention to rise (small moves) but does not pop.Cheers.

Sounds to me like the vacuum line to your locking/unlocking device in the non properly working doors are your problem. As more than one door is effected I would suggest the line/connection at the vacuum pump under the back seat is a good place to start looking. The vacuum pump is literally underneath the back seat inside a foam 'pillow'. The backseat is locked down by two devices where the floor and the seat meat. push the visable tab in and that should release that side. Easiest done with two ppl, one on either side.
