Have a 1997 Camry LE whose RT Front door lock is not responding. It will open and close the other three doors. Drivers side switch will not open it. Using the key will open only three doors. Any ideas? Thanks

 

Each passenger door lock is controlled by two circuits linked together.

The master switch routes 2 wires to the door lock system. By changing polarity of the DC power in the wiring the door lock switch will move one way or the other (lock/unlock).

There is also a 3rd power wire going to each individual door switch. When the individual door switch is used, power goes to the actuator lock based on up or down position of switch (lock/unlock) then routes back to the master control switch via 1 of the 2 wires stated above.

If the individual door switch works for lock and unlock there may be wiring problem with the 2 wire system. If the door switch works for only one position this could also be wiring problem. If neither work may be the actuator is bad.

 

Thanks I appreciate it.

 

This procedure surely work...
