This is a FWD. The electric door locks won't lock or unlock. The security system still works. Could it be the door lock actuator? If so, where is it located? Also, where is the blower door panel actuator located on this model?

I would check the drivers side door lock switch first. check fuses. Do other of the lock switches work?

All doors do the same. Just click and won't lock or unlock.

is that all from the switch on the passengers side. if you do it on the passengers side does it still make the noise? Try to see if they are even trying to lock or unlock by putting your hand over the lock rod and see if it does any thing.

Just to add to the answers, I attached a wire diagram. Check the fuses listed that I circled.

Chances are if you hear the lock click, they switches are working and the actuators are bad.

They are inside the door and attached to the door latch assemblies.

Can you manually lock and unlock the doors?
