FIGURE 3
Check Wiper Blade Mounting Angle (Figure 3)
With the right hand wiper arm assembly in the middle of a wipestroke and the wiper blade assemblies removed, visually check that the blade assembly
mounting pin on each wiper arm is parallel to the windshield. Replace the wiper arm if necessary.
FIGURE 4
Check For Blade Set (Figure 4)
Remove the wiper blade assemblies from the wiper arms being
careful to note orientation for reassembly. Look down the
length of the blade element. The rubber element which
contacts the glass must be on the center line of the blade
assembly +/- 15 degrees. Replace the element if necessary.
