Checking the operation of windshield wipers and washers (Renault 19)

If the windshield washer is faulty, you should start the inspection from the tank located in front of the injection system control unit.



Left: To remove the wiper arm (1), unscrew the mounting nut (2) from the wiper arm shaft (3). To access the shaft mount, remove the cap (4). After winter salt, lubricate the wiper arm shaft with corrosion-resistant oil.

Right: To change the wiper blade, press the tab (arrow) on the wiper blade hinge.

Constant control

• Turn on the ignition.
• Do the windshield wipers work at both speeds and do they return to their original position when turned off?
• Does the intermittent wiper work?
• Does the windshield wiper switch work when pressed once?
• Is water spraying from the windshield washer nozzles?
• Do the rear window wipers and washer work?

Removal the windshield wiper arm

1. Using a flat-head screwdriver, pry up and remove the wiper arm cap.

2. Unscrew the nut.

3. Remove the wiper arm from the shaft.

4. If this is not possible, place a large cloth on both sides of the wiper shaft to protect the hood and air grille.

5. Using a screwdriver inserted from the right and left, lift and remove the wiper arm.

6. Position the wiper arms so that they are parallel to the lower seal of the windshield.

7. Check if they are working and if the left wiper blade does not hit the windshield seal when the wiper is operating.

Note: Recommendation: If it is necessary to install the wiper blade in a different position, loosen the wiper blade arm on the drive shaft, remove it, and then install it in the new position. If you move the wiper blade arm loose in the fastening on the shaft, you can damage the splined connection of the arm axis. If it is necessary to remove both wiper blade arms, mark where each one was installed, since the arms have different lengths and different cap shapes.

Removal the wiper blade

1. Fold back the wiper blade arm.

2. Compress the wiper blade retaining spring until its protrusion comes out of the hole in the arm.



3. Press the wiper blade down and remove it from the arm.

4. When installing the wiper blade, make sure that it is securely fixed to the arm.

Replacing rubber in windshield wiper blades

The rubber of windshield wipers lasts for six months at most. It is cheaper than buying new wipers to replace the rubber on old wipers, for which:

1. Remove the wiper blade.

2. The wiper rubber has notches on one side to accommodate the wiper arm clamp. Press the corresponding bumps in the rubber with your fingernail or a small screwdriver so that the clamps can be released.

3. Remove the windshield wiper rubber with the side metal spring strips.

4. Install the new wiper rubber into the lower wiper arm clips.

5. Slide the spring strips in from the right and left and insert the retaining tabs of the strips into the recesses on the rubber.

6. Press the rubber bulges again to secure them with clamps.

Note: Recommendation: Good cleaning of the glass is especially important on the driver's side. Tip for the budget-conscious: install the wiper blade from the driver's side to the front passenger side, install the wiper blade with new rubber on the driver's side.

Troubleshooting

Malfunction	Cause	Troubleshooting
A. Water and dirt are evenly distributed over the glass.	1. The glass is contaminated with varnish care product, oily residue or insect debris. 2. The rubber bands of the brushes are worn out. 3. The brush holder does not press the brush tightly against the glass.	Apply "Sidol" cleaning agent to the glass, let it dry, and then wipe with a clean cloth. Replace. Bend the end of the brush holder.
B. Untouched water stains remain on the glass.	See A 2.
C. Traces of small drops remain on the cleaned surface.	The angle of the brush rubbers is too sharp.	Replace the brushes.
D. A water film remains on the cleaned glass surface.	Uneven pressure distribution due to bent or faulty wiper blade pressure spring.	Replace the brush.
E. Some areas of the glass surface being cleaned remain untouched.	1. The brush holder contact pressure is too weak. 2. The windshield wiper drive is worn out. 3. The brush holder has become loose on its axis. 4. The brush holder is bent. 5. The brush itself is curved.	Check the clamping pressure. Lightly lubricate the spring, replace the holder if necessary. Check and replace faulty parts. Tighten. Bend it back. Replace.
F. Water remains on the top edge of the glass surface being cleaned.	1. See E 1. 2. See D.
G. The brushes make noise when working.	1. The gap between the brush or plastic connecting part and the brush holder is too large. 2. The brush holder is twisted.	Replace the brush, plastic connector or holder. Carefully rotate the holder to the correct position.
