Mazda CX-9 Owners Manual: Wiper Blades

CAUTION

• Hot waxes applied by automatic car washers have been known to affect the wiper's ability to clean windows.
• To prevent damage to the wiper blades, do not use gasoline, kerosene, paint thinner, or other solvents on or near them.
• When the wiper lever is in the AUTO position and the ignition is switched ON, the wipers may move automatically in the following cases:
  • If the windshield above the rain sensor is touched.
  • If the windshield above the rain sensor is wiped with a cloth.
  • If the windshield is struck with a hand or other object.
  • If the rain sensor is struck with a hand or other object from inside the vehicle.

Be careful not to pinch hands or fingers as it may cause injury, or damage the wipers. When washing or servicing the vehicle, make sure the wiper lever is in the OFF position.

Contamination of either the windshield or the blades with foreign matter can reduce wiper effectiveness. Common sources are insects, tree sap, and hot wax treatments used by some commercial car washes.

If the blades are not wiping properly, clean the window and blades with a good cleaner or mild detergent; then rinse thoroughly with clean water. Repeat if necessary.

Replacing Windshield Wiper Blades

When the wipers no longer clean well, the blades are probably worn or cracked.

Replace them.

CAUTION

• To prevent damage to the wiper arms and other components, do not try to sweep the wiper arm by hand.
• Do not bend the blade rubber unnecessarily when replacing it.

  Otherwise, the metal stiffener in the blade may deform and the windshield wiper operation may be adversely affected.

NOTE When raising both windshield wiper arms, raise the driver's side wiper arm first.

When lowering the wiper arms, slowly lower the wiper arm from the passenger's side first while supporting it with your hand. Forcefully lowering the wiper arms could damage the wiper arm and blade, and may scratch or crack the windshield.

1. Raise the wiper arm.

CAUTION To prevent damage to the windshield let the wiper arm down easily, do not let it slap down on the windshield.

2. Slide the blade component in the direction of the arrow while pressing the wiper arm tab to remove the blade component from the wiper arm.

3. Pull the blade rubber in the direction of the arrow and slide it to a position where the blade holder groove can be checked.

4. Pull the end of the blade rubber from the blade holder groove in the direction of the arrow and remove the blade rubber from the blade holder.

5. Insert the end of the new blade rubber into the groove of the blade holder until it contacts the end of the blade holder.

6. After pulling the blade rubber in the direction of the arrow and sliding the blade rubber to a position to check the blade holder groove, slide the blade rubber end in the opposite direction.

7. Make sure that the blade rubber is correctly installed to the blade holder.

8. Align the wiper arm tabs with the blade component grooves.

9. Align the blade component projection with the wiper arm notch.

10. Slide the blade component and install it to the wiper arm.

11. Slowly lower the wiper arm onto the windshield.

Replacing Rear Window Wiper Blade

When the wiper no longer cleans well, the blade is probably worn or cracked.

Replace it.

CAUTION To prevent damage to the wiper arm and other components, do not move the wiper by hand.

1. Remove the cover and raise the wiper arm.

2. Firmly rotate the wiper blade to the right until it unlocks, then remove the blade.

CAUTION To prevent damage to the rear window, do not let the wiper arm fall on it.

3. Pull down the blade rubber and slide it out of the blade holde

4. Remove the metal stiffeners from the blade rubber and install them in the new blade.

CAUTION Do not bend or discard the stiffeners.

You need to use them again.

5. Carefully insert the new blade rubber.

Then install the blade assembly in the reverse order of removal.
