Power Locks Click to Lock and Unlock by Themselves
 

I'm not sure what this is, but when I have the key in the on position and open and close the drivers door. The power locks click to the locked and then unlocked position. The actual knob doesn't move but it cycles on and off.

Any ideas?

Year of car? Does it have remote controlled locks?

96 Camry 4 banger and no manual locks no remote

What happens when you use the drivers door switch with the key on and door closed, does the knob on the inside of the door move?

If the ign key is on and door is open, if the lock switch is moved to lock, the lock will cycle closed then open.

If manual locks might be a short or other fault in the wiring. Typically this happens between the drivers door and chassis. With constant door usage the wires flex and can break.

Also check for a stuck or sticking door switch ,check all of the door switches.
