The power door lock system has an actuator in each door. The actuator actuates the lock through a linkage. The system is actuated by a control switch on each door. All doors lock and unlock at the same time from any control switch or manually from each door in the conventional manner. Each actuator has an internal circuit breaker. Each internal circuit breaker may require 1-3 minutes in order to reset. The actuator is a serviceable part of the lock assembly.
