BACKLASH: Is it only mine or do all Morgan wiper systems suffer with backlash. i.e. if I set my blades onto the splines in the parked position just kissing the bottom of the window frame, then operate them, they will park a cm or so up from the frame. Gently finger pressure on the blades will take up the play and restore them back to the original starting point. wet or dry makes little difference. Have lubed the shafts just below the splined heads. The flexi drive appears in good condition with no backlash on the motor driving gear.
