My car is a 1984 380 SL. While looking at the car this morning, I noticed that I could manually twist the non-working wiper unit. My feeling is that the wiper blade unit has somehow come loose from the shaft that turns the wipers. My question is: How do you tighten the blade unit so it doesn't slip.? There is a shroud or cap of grey metal around the base of the unit.
Any help would be aprecciated.
