A synchronization system according to the present invention includes a signal generator that provides a "RUN" signal of a predetermined duration simultaneously to two or more windshield wiper motors in response to receipt of position signals generated by the motors. Each motor generates a position signal when the windshield wiper controlled by the motor is at a predetermined position. A gate circuit monitors the output of each motor to determine whether the motor is in the predetermined position. The gate circuit provides a trigger signal to the signal generator of the present invention only when each motor outputs a position signal. The trigger signal causes the signal generator to produce a subsequent "RUN" signal initiating another wipe cycle. Accordingly, the motors begin each cycle in unison.
