Window crank handle busted? It happens a lot when window regulator lubrication dries up, and moisture and debris make their way past the belt molding as a vehicle ages. You put in that extra effort to turn it and it strips the plastic splines, or the handle just cracks entirely. This Dorman OE FIX window crank handle replaces the original equipment handle, but the splines and arm are upgraded to metal to increase durability and longevity. Replace that broken handle with this one and you can hopefully avoid shopping for a new one again. Note the window crank knob differs slightly from the OEM design—for a matched appearance, order enough cranks for the entire vehicles.
