Wiper Blade: Inspection

Check and clean the rubber assembly windshield wiper.
CAUTION:
- Do not use organic solvent-based cleaner. Failure to do so can cause rubber part deterioration.
- Do not use the cleaner that includes silicone oil. Failure to do so can cause chattering sound.
- Clean rubber parts using a soft cloth or paper towel dampened with windshield washer fluid or mild synthetic detergent that is diluted two times or more.
Replace the rubber assembly windshield 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 windshield 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 windshield wiper again. If a chattering sound or insufficient wiping occurs, perform the procedures again.
If defective is not improved after performing step 1 without replacing the rubber assembly windshield wiper, replace the rubber assembly windshield wiper with a new part.
If defective is still not improved after operating the washer system again, replace the blade assembly windshield wiper with a new part.
