A drive for a tandem windshield wiper system including a driver's side wiper blade and a passenger side wiper blade wherein the driver's primary vision area is wiped twice during each tandem stroke of the wiper blades. The drive includes a unidirectional electric motor with a crank arm, a rotatable drive plate connected to the passenger's side wiper blade, a driver's side crank arm connected to the driver's side wiper blade, a transverse drive link connected to the motor crank arm and linearly reciprocated thereby, linkage between the drive link and the drive plate operative to convert reciprocation of the drive link to angular oscillation of the drive plate and passenger side wiper blade, and a transverse operating link between the drive plate and the driver's side crank arm operative to transfer angular oscillation of the drive plate to the crank arm and driver's side wiper blade in tandem fashion.
