Fixes issues with a malfunctioning window washer.
In modern vehicles, a malfunctioning windshield washer can be a nuisance during inclement weather. Here are some common reasons and solutions for this issue.
One of the most frequent causes is contamination of the windshield washer system. This can occur due to using low-quality washer fluid, exposure to dirt and debris from the road, or lack of regular maintenance and cleaning. Contaminants such as dead insects, dust, pollen, and lime deposits can accumulate in the nozzles, causing clogging.
Clogged nozzles, often located in the upper area of the engine hood, can prevent the windshield washer from functioning properly. In older vehicles, a fine needle can be used to clean the nozzles carefully without applying force. In modern cars, which may use 'fan nozzles' or 'micro-sprayers' with a finer structure, compressed air can be used to unclog the nozzles.
Another potential issue lies with the hoses. Over time, the rubber in the hoses can harden and crack, causing leaks or blockages. To check the hoses, they should be disconnected from the washer fluid reservoir and the pump, then squeezed to check for any cracks or leaks. If cracks or leaks are found, the hoses should be replaced immediately.
Frozen wiper blades can also prevent the windshield washer from working. A warm garage or a long drive can help thaw the frozen fluid. If the wiper is activated and the wiper motor can't turn, replacing the windshield wiper motor might be necessary.
In some cases, the problem might be with the pump itself. If suspected, it's best to take the vehicle to a professional mechanic for further diagnosis and repair. If the motor is silent when the windshield washer is activated, it might be defective.
In winter, frozen windshield washer fluid can cause the windshield washer to stop working. It's important to inspect the windshield washer container for cracks and holes, as water expands when freezing. If the windshield washer still isn't working after cleaning the nozzles and checking the hoses, it's worth investigating whether the pump or the motor might be the culprit.
Lastly, very rarely, contaminated windshield washer fluid can cause a windshield washer system failure. If there are contaminants, the fluid should be replaced and the reservoir thoroughly cleaned. If contacts are corroded, contact spray might help.
Regular maintenance and cleaning of the windshield washer system can help prevent these issues, ensuring clear visibility on the road during adverse weather conditions.
