What causes the automatic headlight washer rod to not retract?

[JaceRose]

The reasons why the automatic headlight washer rod does not retract are: 1. The headlight washer device is difficult to reset after being blocked by foreign objects. Check if there are any foreign objects stuck inside the washer device. The most common foreign objects are leaves or small stones. After cleaning, normal use can be restored; 2. In winter, when temperatures are low, if the windshield washer fluid is not properly treated for antifreeze, it can freeze directly inside the headlight washer device, preventing the headlight washer device from moving up and down. Method for using the headlight washer device: When the ignition switch is in the 'on' position, turn on the high beams, then pull the wiper control lever toward the driver and hold it for more than 1 second. The front headlight washer device and the windshield washer device will work simultaneously. Once the wiper control lever is released, the windshield washer device will stop spraying the cleaning fluid. Do not use the headlight washer device if there is no cleaning fluid to avoid overheating the motor.

The headlight washer arm on my car often fails to retract, especially in winter, with the most direct cause being water freezing and getting stuck there. When the headlight washer function is activated, it freezes and extends but can't retract. This needs to be addressed promptly, otherwise the arm might crack from freezing or the motor could burn out. I usually use hot air to blow into the engine compartment to melt the ice, but avoid pouring hot water directly as it can damage the parts. A long-term solution is to check if the washer fluid contains antifreeze and regularly spray some lubricant on the moving parts. When washing the car, also be careful not to let mud clog the nozzles. If it gets stuck, try manually pushing it. Neglecting such small issues can lead to headlight washer failure while driving, which affects nighttime visibility and is quite dangerous. It's recommended to perform preventive maintenance regularly to avoid trouble.

From experience, the failure of the headlight washer nozzle to retract is often due to mechanical issues, such as deformation of the nozzle arm or motor jamming. Once, I found that dirt had accumulated in the retraction track—dried mud residue from car washing had hardened like a solid block, preventing the nozzle from retracting. Another common issue is signal problems with the control module, such as loose wire connections or relay failures, which require checking voltage with a multimeter. If you're attempting a DIY fix, start by cleaning visible dirt with a soft cloth and gently pushing the nozzle to see if it resets—avoid using excessive force to prevent breakage. If that doesn't work, professional repair is necessary, where the shop will inspect both the mechanical structure and electronic system. Regular maintenance can prevent this issue, such as lubricating moving parts every season to ensure smooth system operation and reduce unexpected delays during travel.

The cleaning rod not retracting is commonly caused by blockages or wear. I've encountered mud clogging the pipes, with improper cleaning being the main reason. The solution is simple: manually push it back or spray warm water to soften the dirt. For prevention, choose suitable cleaning fluid to avoid corroding parts and avoid frequent use during heavy rain. Cover the headlight covers when parking outdoors to prevent dust—these small habits can extend service life and avoid repair costs.
