2006 DODGE SPRINTER 2500 Visibilitywiper Problems

THE LEFT DRIVERS SIDE ELECTRIC WINDOW HAS A BROKEN PIECE OF NYLON/PLASTIC THAT IS ABOUT 11/2" X 1/2", THAT IS HELD IN PLACE BY A RIVET THAT APPEARS TO LOOK LIKE A NAIL HEAD ON THE METAL WINDOW REGULATOR ARM. THIS FLIMSY PLASTIC PART BROKE INTO TWO PIECES WHICH ALLOWS THE ARM OF THE WINDOW REGULATOR TO POP OUT OF THE TRACK BELOW THE WINDOW, AND THE WINDOW FALLS DOWN AND STAYS OPEN. WHEN THIS HAPPENS IT CREATES NOISE, ALLOWS BAD WEATHER TO ENTER THE VEHICLE, AND CREATES A VERY DISTRACTING SITUATION FOR DRIVING, ESPECIALLY ON THE INTERSTATE HIGHWAY SYSTEM. THERE IS NO FIX FOR THIS SMALL PART ONLY A NEW REGULATOR WITH THE SAME FLIMSY PIECE OF PLASTIC. THE WINDOW REGULATOR COSTS BETWEEN $219 AND $224 PLUS TAX AND SHIPPING. THE COST TO INSTALL IT IS ANOTHER 200+ DOLLARS. THIS REGULATOR SUFFERS FROM POOR DESIGN AND SHOULD NOT BREAK...
