Causes of car injectors malfunction

    The water sprays in the car are one of the essential parts that are important to clean the windshield and remove the dust and dirt accumulated on it. The operation in the control panel, as the water flows through the tubes connected to the car atomizers, and the atomizers move up and down to clean the glass, and the atomizers may malfunction for various reasons, and this article explains the causes of car atomizers malfunctions and problems, as well as explaining how to fix them.

Causes of car injectors malfunction

1. Pump motor failure

    A malfunction in the electric motor of the car windshield sprayer pump causes the sprayers to stop working and not to spray water on the glass, due to the wear of the pump motor, or a defect in its electrical circuit, and a leak in the pump tubes can cause a malfunction in the windshield. Nebulizers, such as the separation of the pipes under the car, or cracks or fractures in the water tank.

2. Freezing water in the pump

    The freezing of the water in the atomizer pump when the temperature of the place is low can cause the atomizers to malfunction, and the problem can be addressed by placing the car in a warm garage, and leaving the car for hours until the water melts, and warm water can be poured on the sides of the windshield to accelerate the melting of snow and try to run the pump to make sure the problem is resolved.

3. Clogged nebulizer nozzle

    Clogged nebulizer nozzles can cause no water to escape when the pump is running. The problem can be easily resolved by cleaning the nebulizer nozzle by applying the following steps:

  • Lift the nebulizer cap, inspect the tubing all the way to the tank, and check where the blockage is.
  • Disconnect the pipes and operate the pump to make sure the water is out and there is no blockage in the pump nozzle, clean it if it is clogged with a small pin, and remove the dirt accumulated on it, or inside the pipes.

4. The power supply to the nebulizer pump is disconnected

    The disconnection of the electrical current from the nebulizer pump may cause the pump to stop working, and this can be confirmed if the pump sound is not heard when the nebulizer is running, by checking the current using a voltmeter, by disconnecting the electrical wires of the pump, and checking the electrical current, as the reading appears in the number 12 It is also preferable to resort to a specialist when there is no reading, to change the nebulizer pump.

5. The tank has run out of water

    The lack of water in the nebulizer pump can cause the nebulizer to stop working, and this can be confirmed by the following:

  • Find the tank and check the water level in it, and make sure to refill it if it is empty, or increase the water level if it is low.
  • Check the voltage associated with the control unit of the nebulizer, if there is voltage in the pump, and it is preferable to check the voltage between the pump connector and the control unit, as it is more susceptible to damage and corrosion.

6. Uneven water distribution

    The problem of uneven water scattering from the nebulizer appears when it is operating and pulling its lever, due to blockage of pipelines or the pump nozzle, or because the pump malfunctions or reduces its operating capacity due to continuous wear when the water level is low inside it, as the water must be distributed evenly when Run the sprayer to clean the windshield of the car.

7. Cracks in pipes or tanks

    The nebulizer tubes or tanks may crack or corrode over time, causing the nebulizer to malfunction and stop working. This can be confirmed by the following:

  • Check for any cracks or leaks in the nebulizer tubes, or the presence of a leak in the tank, by opening the car hood and fixing it well.
  • Locate the tank and tubes, and start the inspection from the nozzle of the tubes and tank, to the point of contact with the nebulizer, making sure that there are no cracks or holes.
  • Resorting to the mechanic to repair the pipes or leakage of the tank, or change it if the damage is significant.

8. Water jet damage

Damage or obstructions in the water jet can cause the water not to escape while the nebulizer is operating. This problem can be solved by soaking or changing it as follows:

  • Separate the tube attached to the jet from the bottom, pressing it directly and pulling it.
  • Detach the jet from the windshield of the vehicle using the pliers, then press and pull it up.
  • Soak the jet in a bowl containing a large amount of vinegar for several minutes; To clean the blockage, remove the dirt accumulated in it, then wash it with water and make sure that all the dirt accumulated inside it is removed.
  • Reinstall the jet correctly, turn it on to make sure the problem is resolved, or change it when needed.
