With the aid of a pin, unclog the clogged windshield washer nozzle. Then, blow the debris back through the hose with compressed air.
- If the pump is running but no fluid is coming out, your windshield washer nozzles are probably clogged.
- A spherical one-way check valve or a plastic barbed connector can be found somewhere along the path. Retry the washer after cutting the tubing there.
- You may tell the nozzles are clogged if fluid squirts out. Push a tiny pin into the nozzles to remove any debris, then blow the obstruction back down the line and out the end you disconnected.

How does a Volkswagen Jetta use wiper fluid?
Did you realize? The wipers never rest on the same edge twice in a row when you switch them off; instead, the edges alternate. This prolongs wiper life and lessens wiper wear.
Please keep in mind:
- In cold weather, never use the wipers or washers without first defrosting the windshield. The window washer solution could freeze, obstructing view.
- Always keep all windows and the windshield wiper blades clean.
- Wiper blades that are worn out or unclean can impair visibility and raise the possibility of crashes and catastrophic injuries.
- Wiper blades that are worn, broken, or aren’t keeping the windshield clear should always be replaced.
turning on the rear wiper Push the lever (7) one click to the ON position while moving it away from you to turn it on. If you press the lever away from you when it is in the ON position and hold it there for however long (8), washer fluid will spray out the back window.
If the front wipers are also on when you put the car in reverse, the rear wiper will also turn on automatically. It’s not necessary to turn on the back wiper. After all, it seems sense that if it’s pouring at the front of the car, it’s presumably also raining at the back.
setting the wipers on your windshield Driving in the rain is common, but it’s not always a constant downpour. Your Volkswagen’s windshield wipers have four settings as a result. The first option is an effortless intermittent setting. Simply raise the stalk one click from the OFF position ((0)). (1). The wipe interval can then be changed by turning the switch at the top of the stalk (6) to the left for a longer period or the right for a shorter one. “Left, Less; Right, Rain” comes to mind.
Two clicks up (2) and three clicks up (3) provide you slow, continuous wiping and quick, continuous wiping, respectively, if you want to take charge. It must be pouring rain right now. You can perform a single wipe by depressing the stalk once (4) starting from the OFF position. Or, for a quicker wipe, hold the lever down for two seconds. When you release the stalk, the wipers will continue to operate.
Pull the stalk in your direction to wash the windshield; the washer fluid will spray for however long you are pulling the stalk.
How should a windshield wiper washer be used?
For low-speed wiper operation, turn the multifunction lever’s end to the first detent past the intermittent settings, or for high-speed wiper operation, turn it to the second detent past the intermittent settings.
Intermittent Wipers
When the weather permits, use one of the four intermittent wiper settings. The delay can be adjusted to range from a maximum of about 36 seconds between cycles (first detent) at driving speeds exceeding 10 mph (16 km/h) to a cycle every one second (fourth detent). Delay times will be increased if the vehicle is travelling less than 10 mph (16 km/h).
Windshield Washers
Push on the lever’s end (facing the steering wheel) and hold to operate the washer. When the end of the lever is released while the wipers are in the intermittent setting, they will switch on and run for a number of cycles before returning to the previously chosen intermittent interval.
The wipers will run for numerous cycles before turning off if the end of the lever is pulled with the wipers in the off position.
Note:
Since the washer pump is not turned on by the mist feature, no washer fluid will spray over the windshield. Spraying washer fluid onto the windshield requires using the wash function.
How does the VW rain sensor function?
Depending on how much rain is falling, the rain sensors automatically adjust the frequency of your windscreen wipers.
Because of our rain sensors, you won’t need to continuously turn on and off your wipers or change their speed to account for how hard it is raining. This innovative mechanism controls the wiper in accordance with the amount of rain falling on the windscreen using an LED sensor installed behind your inside mirror.
Depending on how sensitive you want the rain sensor to be, you can select several levels. The wipers will only remove a few spots of rain if you select the most sensitive option, while the least sensitive setting will take a little longer to get going. Even worrying about reversing is not necessary. When the sensor is activated and you shift into reverse, the back wipers will start to clear any rain.
A number of infrared light-emitting diodes (LEDs) and a central photodiode make up the sensor system. The windscreen reflects the LEDs’ light back onto the photo sensor. The sensor receives less light the more water drops there are on the windscreen. An electronic control unit receives this data and modifies the windscreen wiper’s wash intervals accordingly.
Additionally, due to the design, the effectiveness of the windscreen is not affected by dirt, minor flaws, or aging. Because the rain sensor conducts the labor-intensive work, you’ll find driving in wet circumstances safer and more comfortable because you can focus entirely on the road. It’s especially helpful when your sight is suddenly reduced, like when passing truckers on a slick road.
How can I tell if the windshield washer pump is operating properly?
When you activate the windshield washer fluid to spray over your windshield, the washer pump emits a characteristic sound. When you press the button, if no sound is made and no fluid sprays over your windshield, the pump is either damaged or isn’t getting electricity. If this is the situation, make sure the fuse that powers the washer pump isn’t burned out and replace it if it is. To replace the windshield washer pump, though, you’ll need to get in touch with a nearby ASE-certified mechanic if the fuse is not the issue.
Why don’t my water jets function?
Windscreen washer pumps may experience issues that limit how efficiently the washers function or prevent them from spraying at all. Common examples include:
Dirt in the Nozzles
Clogged washer nozzles are one of the most frequent causes of screenwash problems. This occurs when tiny dust and dirt particles enter the nozzles that are affixed to the top of the bonnet and block the spray from functioning.
To clear the obstruction, poke about within the nozzles with a safety pin or needle. To completely eliminate the obstruction, you might need to spray the screenwash a few times.
Clogged Washer Feed Tubes
The feed tubes connecting the reservoir to the nozzles can occasionally become clogged with dirt and other debris. Intermittent screenwashing or a complete lack of it altogether are signs of a clogged washer hose.
Start by removing the hoses from the windshield washer reservoir. You’ll need a screwdriver to free them up because clamps and a rubber grommet are holding them in place. After that, use an airline or a can of pressurized air to spray down the nozzle and drive the particles out of the washer hose’s end. Avoid washing down the hose towards the nozzles; doing so may force dirt and debris into the nozzle head, making it more difficult to clean.
Faulty Windscreen Washer Pump
If your washer still performs poorly after you’ve cleaned the nozzles and hoses, there might be an issue with the pump. The steps to troubleshoot and identify a windscreen washer pump are as follows:
- Turn off the power and reach the washer reservoir’s bottom if the pump isn’t functioning. The problem might be caused by soiled electrical connections, in which case a quick clean would be sufficient.
- If not, you’ll need to remove the reservoir casing’s two screws that typically hold the motor and pump to it. After doing this, restart the ignition and check with an electrical tester that the pump and motor are receiving electricity.
- Replace the windscreen washer pump if there is electricity; we’ll explain you how to accomplish this below.
- You might need to replace the fuse, which is a fairly simple procedure, if there is no electricity. Simply locate the fuse box using your manual, then swap out the washer pump fuse with a fresh one.
- While you put your hand on the reservoir, have someone else turn on the washers inside the car. Check to see if you can feel any vibrations when the switch is turned on and listen for the pump to start buzzing. If you can, there’s probably a clog or a leak from the reservoir; if you can’t, the pump is broken.
Describe the wiper switch.
Your wiper motor and wiper blades require a signal from your car’s windshield wiper switch in order to clean your windshield. This switch is crucial for the clarity of your driving vision and the cleanliness of your windshield because it also regulates the speed at which your wipers wipe.
