If the wipers do not clean the glass well, wash the glass and wiper blades with an effective cleaner or mild detergent, then rinse them thoroughly with clean water. Repeat the treatment of the glass and wipers if necessary.
If your windshield wiper no longer cleans the glass well, the possible cause is worn or cracked blades. Replace worn blades or brushes.
1. Raise the wiper arm and rotate the blade relative to the hinge to expose the plastic retaining tab.
Fig. 1.187. Windshield wiper blade replacement diagram
Move the brush down (in the direction of the arrow, as shown in Figure 1.187). Then remove the blade from the wiper arm.
2. Bend down the end of the rubber blade and pull it out of the holder.
3. Remove the spring ribs from the rubber blade and insert them into the new brush blade.
4. Carefully insert the new rubber blade. Then install the blade assembly onto the wiper arm in the reverse order.
Important! Do not bend or discard the spring ribs. They are reusable. Failure to install the spring ribs into the blade may result in poor glass cleaning performance. Do not use the spring ribs removed from the left wiper blade to install them into the right blade, and vice versa. Make sure to install the spring ribs into the new wiper blade so that the blade curve remains the same as the old blade.
