The present invention relates to a wiper motor drive system that includes a motor, an output shaft operatively connected to a wiper blade, and a breakaway clutch operatively connected between the motor and output shaft. The breakaway clutch includes a torque-sensitive releasable locking mechanism having a first position wherein torque is translated from the motor to the output shaft through the breakaway clutch to drive the wiper blade across a surface to be wiped, and a second position wherein torque is interrupted between the motor and the output shaft in response to a predetermined rotational torque differential acting on the output shaft, with the locking mechanism being movable back to the first position when the differential torque is reduced on the output shaft.
