ON INVOLVED VEHICLES, THE CONNECTION BETWEEN THE STEERING CONTROL SHAFT AND THE INPUT SHAFT ON THE STEERING GEAR BOX MAY BE DEFECTIVE. THE YOKE ON THE SHAFT MAY LOOSEN, ALLOWING THE SPLINED SURFACES ON THE YOKE AND SHAFT TO WEAR. CONTINUED OPERATION MAY RESULT IN WEAR AND EVENTUAL ROTATIONAL SLIPPAGE OF THE JOINT.
THE YOKE WILL BE REPAIRED OR THE YOKE AND INPUT SHAFT WILL BE REPLACED, IF NECESSARY.
THE PARK/RUN VALVE IN THE WINDSHIELD WIPER MOTOR MAY STICK IN THE PARK POSITION. AN OUT OF BALANCE DIMENSION IN THE CYLINDER RESULTED IN AN UNDERSIZED BORE WHICH MAY CAUSE THE PLUNGER TO STICK. THEREFORE, THE WIPER MOTOR MAY FAIL TO START.
THE DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE WINDSHIELD WIPER MOTORS FOR CONVENTIONAL MODELS. ALSO, THE CONTROL VALVES ON THE DASH WILL BE REPLACED AT NO COST TO OWNER.
