I have a 2008 Camry Hybrid with about 125k miles

A few thousand miles ago the door locks have been displaying portions of the following issues and then finally ended up with all these issues described:

Driver door lock: (OK)
- Opening door when in locked state by using latch, works
- Manually toggling lock/unlock on the door works
- Power door lock switch locks and unlocks door

Front passenger door lock: (Issue)
- Opening door when in locked state by using latch, works
- Power door lock switch on this door or driver door, does NOT lock/unlock door
- Manually toggling lock/unlock on the door works

Rear right door lock: (Intermittent Issue)
- Opening door when in locked state by using latch, does NOT work
- Power door lock switch on driver and passenger doors intermittently fail to lock/unlock this door
- Manually toggling lock/unlock on the door works

Rear left door lock: (Issue)
- Opening door when in locked state by using latch, does NOT open the door
- Power door lock switch on driver and passenger door does NOT lock/unlock this door
- Manually toggling lock/unlock on the door works

Any ideas on what specific parts would need to be replaced? I'd want to purchase them used or via Ebay to save money prior to taking the car to the shop

Thanks!

 

Front passenger door lock: (Issue)
- Power door lock switch on this door or driver door, does NOT lock/unlock door

faulty switch lock switch / lock activator /faulty earth/
wire to door and car wiring interior broken

door card off / check wiring and visually inspect lock activator motor works

Rear right door lock: (Intermittent Issue)
- Opening door when in locked state by using latch, does NOT work
- Power door lock switch on driver and passenger doors intermittently fail to lock/unlock this door

does this door have a child proof lock option
door card off / check wiring and visually inspect lock activator motor works

also the lock lever connections have not slipped off
faulty switch lock switch / lock activator /faulty earth/
wire to door and car wiring interior broken

Passenger door lock switches have two sources of +12V power. This allows usage of both the drivers door and individual switches.

Each passenger switch has three wires. Two go to the drivers switch (+/- 12v) and one to the main power relay (+12v).

When the drivers door switch is used to activate a passenger door lock, +/- 12v goes to that lock via the two wires. The polarity if the wires depends on the position of the switch (lock or unlock). Changing polarity to the door lock motor moves changes it direction of operation and thus lock or unlock.

For individual door lock operation. When the individual door lock switch is used, +12v from the power relay power source is directed via the individual switch position to one or the other wire of the locking motor to lock either lock or unlock the door. The return wire (-12v) is then directed via the door lock switch one of the two wires going to the drivers door.

If the drivers door switches are able to control all locks properly, the wiring between this switch and passengers switches would seem to be OK.

This leaves the +12V power wiring from the main power relay and drivers switches as a problem source.

 

When you speak of the lock activator, is that the actuator?

Thanks!

 

Same.
