1. Run the wiper arm and the blade assemblies to the mid-wipe position.
2. Remove the wiper blades from the wiper arms. Refer to Windshield Wiper Blade Replacement .
3. Attach a scale to the end of the wiper arm and measure the force required to lift the wiper arm perpendicular to the windshield to the normal working height (the height with the blade assembly attached).



4. If the force required is not within the specifications given below, the wiper arm assembly should be replaced:

Tip Pressure -- 7.8-9.5 Newtons (28-34 Ounces)

Remove the wiper arm blades from the wiper arm assemblies, 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 centerline of the blade assembly +/- 15 degrees. Replace the element if necessary. Refer to Wiper Blade Element Replacement .
