A windshield wiper drive assembly comprising:

• a motor assembly comprising:
• an electric motor coupled to a reduction gearbox having a gearbox output shaft and a drive cam mounted onto said gearbox output shaft;
• a first rigid cable sheath mount connected to said reduction gear-box;
• a wiper mounting plate having a wiper coupling shaft rotatable mounted through an aperture formed therethrough, a first end of said coupling shaft having a first lever arm end of a rigid lever arm rigidly connected thereto, said lever arm extending radially from said wiper coupling shaft;
• a second rigid cable sheath mount connected to said mounting plate;
• and
• a push/pull cable drive mechanism including a length of cable, a cable sheath and a cable actuation mechanism, said cable being of a length longer than said cable sheath and slidabLy positioned through said cable sheath, said cable sheath having a first cable sheath end and a second cable sheath end, said cable actuation mechanism including a roller shaft coupled to a first cable end of said cable, said roller shaft having a roller wheel positioned at a first roller shaft end thereof and a compression spring positioned over a portion thereof, said roller shaft being positioned with respect to said first cable sheath mount and said drive cam in a manner such that said roller wheel is urged against said drive cam by a spring force generated by said spring, a second cable end of said cable being attached to a second lever end of said lever in a manner such that movement of said roller shaft causes a corresponding movement of said lever arm.
