My 308 estate has developed an intermittent locking problem. It will lock all the doors except the drivers door. Any ideas?

Probably the plastc clip the door lock rod goes thru broke.

sounds like the lock actuator in the driver door has failed, probably have to replace the actuator, but first check the fuses for the locks, chevy has a habit of using a fuse for the drivers door that doesnt power the other doors. If the fuses are ok, then its probably the actuator

Intermittent door ajar switch contacts.

reset the central locking system by locking car with key in drivers door and hold key over for 30 secs.then pressing and holding down unlock button on keypad OR unlock door with key and hold key over 30secs (windows may go down, thats okay,some cars are fitted with auto windows)then press and hold lock button on keypad.making sure that in both cases you know the keyfob battery is in good nick....should reset system

we have a 08 1500 crewcab chevy that all the power door locks worked excepted the drivers door. We started to look at that door power lock actuater and now the passenger power door lock does not work. Could the trouble be something other than actuaters?

When you use your remote or insert your key in the Drivers Front door all the door locks should work at the same time by the door lock motors electrically. If you have to manually unlock the door because it will not lock or unlock by the lock motor, you need a door lock motor. The drivers and passengers front door can unlocked with the key manually. The rear doors you have to pull up the latch. If no doors unlock electrically with the remote or drivers door lock, intermittantly or all the time, you will need a Central Locking Electronic Control Module. You will hear the "beep" but no door locks will fire at all. If you have odd door locks not working intermittantly you need a new door lock motor for each door lock that malfunctions. You can hear of the door locks are working electrically. Yes, they are common problem. If you can hear the door lock working but the door still doesn't unlock you need to take the door panel off and lubricate the door latch assembly and work the lock, loosening it up. This is common as well.

Hi there, this is a very common fault, you need to replace the drivers door actuator to stop the noise, ive done loads of these. hope this helps.

dont blame the idiot,we all make stupid mistakes without thinking and iam no exception,remove door trim and oil the solonoid with a oil can not a silly sunday mechanic spray and let it soak in as its working but i think its just a bit sticky with wear and dirt ingress hence it locks but doesnt unlock which might need a bit more power,oil the whole lot lock and all
