Wiper Blade: Inspection

Check and clean the rubber assembly wiper.
CAUTION:
- Do not use organic solvent-based cleaner when cleaning rubber parts in order to avoid rubber part deterioration.
- Clean rubber parts using a soft cloth or paper towel dampened with windshield washer fluid or mild synthetic detergent.
Replace the rubber assembly wiper if rubber part hardening, deformation or damage is found.
Operate the washer system to check if a chattering sound or insufficient wiping occurs.
If a chattering sound or insufficient wiping occurs, perform the following procedures.
1. Make sure that the blade assembly wiper is not deformed and the movable part moves smoothly.
2. Remove oil film and dirt from the glass.
  CAUTION:
  - When powder-type glass cleaner is used, use after having been dissolved in water sufficiently. If it is used in less water, the glass surface may be damaged.
  - Clean the glass surface using a soft cloth or sponge with glass cleaner.
3. Operate the washer system again. If a chattering sound or insufficient wiping occurs, perform the procedures again.
If the rubber assembly wiper has not been replaced and the defective cannot be improved by performing step 1), replace the rubber assembly wiper with a new part.
Activate the washer system again, and if the defective cannot be improved, replace the blade assembly wiper with a new part.
