My locks are automatically re-locking. They will not stay in the locked position

What is your question?

To get into the car i have to hold the key in the unlock position and the pull the handle. When on the inside you have to hold it in the unlock position and then lift the handle while its still in the unlock position. You can here and see that every time you unlock it, it automatically clicks back into lock. This only happens from the driver side ; which controls all of the doors locks. Any help ; suggestions ?
