4. Leaking hose

If the pump is working, but windscreen washer still does not work, you should check the hoses. If they are cracked, loose or leaking, they must be replaced. An exchange is also recommended if the elasticity of the rubber hose at the connection point to the nozzle decreases. However, the hoses can also have easily fallen off due to vibrations in the engine compartment.

Rodent Damage: If bite marks or the like are discovered, there is a high probability that a rodent has let off steam in the engine compartment of your vehicle. Then it is important to carefully examine all other cables and hoses for damage, including electric wires for the windshield washer pump.

Diagnosis: You don’t have to disassemble the engine compartment to check for a leaking hose. Park your vehicle on a dry pavement and turn on the windshield washer for a few seconds. Now look under the front of your vehicle, if you see a puddle forming then there is a leak, otherwise problem lies somewhere else.

Note: Keep the air-conditioning off in your vehicle when diagnosing a leaking hose, as condensation from the evaporator coil is also drained under the vehicle.

Conclusion

I hope all of these steps help you fix the windshield wiper fluid not coming out issue as easily as possible. If after all of this your wiper fluid still hasn’t returned, it may be time to replace the whole assembly.

Got a problem with windshield wipers not touching the glass? We also wrote a DIY guide about that! Thanks for reading this guide on windshield wipers fluid spray and have a great day!

Part 2 of 2: Installing the new windshield washer nozzle

Step 1: Attach the nozzle. Pop in the new washer nozzle into the same place you removed the old one from. This will be either be on the vehicle body, on the back of the hood, or on the wiper arm.

  • Note: If you had to remove a hood cover, you will need to reinstall the cover. The cover clicks back onto the hood, or you may need to install screws into the hood to secure it.

Step 2: Attach the line onto the new washer nozzle. If the line had a retaining clamp, use needle nosed pliers to put the retainer clamp back onto the line. Install the screw into the washer nozzle if you had to remove a screw.

Step 3: Reattach the heater harness (if applicable). Connect the harness to the washer nozzle. If you had to cut the harness to remove the washer nozzle, then use wire strippers to strip the wires on the new washer nozzle.

Step 4: Reconnect the heater harness wires. If you had to cut the wires, use butt connectors with heat shrinking tubes to connect the harness wires to the washer nozzle. To do this, get two butt connectors for the size of the wires. Use a wire crimping tool to crimp the wires to the butt connectors. Pull on the wires to make sure that they will not come apart.

Step 5: Test the nozzle. Turn the ignition to the accessory or run position. Operate the windshield washer nozzle switch or lever. Watch the fluid coming out of the nozzle. The washer fluid should spray a strong mist onto the windshield.

If you have heated washer nozzles, operate the heater on the nozzle. Use a raytek gun to check the temperature of the nozzle. The nozzle should heat up as the washer fluid is spraying out of it.

If the windshield washer nozzle continues to malfunction after replacing it, then there may be an issue with the windshield washer nozzle, or a possible electrical issue with the washer nozzle motor. If the problem persists, then seek help from one of the certified mechanics at YourMechanic, who can replace the windshield washer nozzle and diagnose any problems.

Check the Fuse

With the car parked in a quiet place, operate the window washer and listen for the whirring of the pump.

  • If there’s no sound, head right for the fuse box.
  • If the fuse is blown, it’s usually a sign of a dead pump motor or one that’s ready to check out. If it blows again, replace the motor.

7. Faulty switch

You turn on the switch that activates the windshield washer system in your car, but nothing happens, the pump is not working and you don’t see any volts on multimeter at the pump’s electrical connector. In rare cases, this could happen due to faulty switch. Diagnosing this problem requires removal of the switch from vehicle’s interior and then tested with a multimeter.

3. Blown washer pump fuse

Your car electrical car accessories are protected by a fuse to prevent shorts and overloading of electricity.

If the fuse of your wiper blows, then you would experience the windshield wiper fluid not coming out of the nozzles.

A blown wiper fuse is easy to replace and only requires a few minutes. To fix the problem, just follow these simple steps:

What you’ll need:

  1. Test light
  2. Replacement fuse of the same amperage as your original one.
  3. Fuse Puller

Most cars have at least two fuse boxes. One is located under the hood, the other one inside the car near the passenger side of the dashboard.

You can find the location of the fuse on the fuse box cover or in the owner’s manual.

Step 1: Find the blown fuse

A test light or circuit tester: If your car has a test light, you can easily find the blown fuse by following these steps. Otherwise, a circuit tester will do the job just as well.

Step 2: Remove the blown fuse and replace it with the new one of a similar amp rating

For example, if you have a 15 amp fuse that blew in your wiper circuit, you need to get another 15 amp fuse from the auto parts store.

If this fuse also blows, you may need to replace a component in the circuit with one compatible with your fuse rating.

Step 3: Test it again

Reattach the wiper fluid line and turn on the wipers. Spray some fluid to make sure everything works fine.

If there is still nothing coming out, it is time to take a closer look at the spray pump.

Types of Windshield Washer Nozzle Kits

There are two main types of windshield washer nozzle kits, including:

Universal Windshield Washer Nozzle Kit

This type of nozzle kit works for most vehicles. An example of a universal windshield washer nozzle kit is the Hypersonic Universal Car Windshield Washer. This windshield nozzle suits all kinds of vehicles. The product cleans windscreens faster than most nozzle kits. It has a dual-hole that ensures that its washing fluid hits every part of a vehicle’s windscreen in the shortest time possible.

Check Power

If the fuse is good but the pump doesn’t run, disconnect the connector at the pump and check for power with a volt meter.

  • With the washer switch on, it should read 12 volts. If you don’t hear the pump and the fuse is OK, the problem is usually a poor electrical connection at the pump or a bad pump.

Remove the pump wire connector and have a friend operate the pump switch while you check for 12 volts with a digital meter at the connector.

  • If you don’t have voltage, the problem is probably in the washer switch or the wiring. That’s the time to take the vehicle to a pro.
  • If you have voltage, clean the terminals and coat them with dielectric silicone grease.

Try the pump again. If it works, your problem is solved. If it doesn’t, replace the pump. The main cause of pump failure is repeatedly running the motor while the reservoir is empty. So try to keep your reservoir full to avoid dealing with replacing a bad one.

Step 3: Make sure the washer nozzle jets are free

Step 3: Make sure the washer nozzle jets are free

The problem could be that your windshield wiper nozzles are clogged. Polish can easily block these nozzles. The location of the nozzle jets varies from car to car. Look around the base of your front windshield for yours.  If it’s the rear wiper jets that won’t work, then check near the topside of the rear window for the wiper jets. Once you’ve located them, use a straight pen to clear out the jets.

Hopefully that gave you some insight into the cause of the problem.  If so, congratulations!  Job well done.
