Why is the Jetta's windshield wiper not spraying water?
3 Answers
Jetta's windshield wiper not spraying water could be due to: 1. Clogged wiper nozzles or detached tubing; 2. Blown fuse; 3. Lack of windshield washer fluid. Solutions for wiper not spraying water: 1. Use a sewing needle, pin, or thin wire to unclog the spray nozzle; 2. Add windshield washer fluid, replace damaged hoses, and tighten loose connections; 3. Repair or replace the motor and its wiring. The 2021 Jetta VA3 features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.5L naturally aspirated engine, producing a maximum horsepower of 112 PS, a maximum power of 82 kW, and a maximum torque of 145 Nm, paired with a manual transmission.
Having repaired Jettas for over a decade, I know windshield washer failures usually boil down to a few causes. Start simple: check if the reservoir's empty—pop open the blue cap on the left side of the engine bay to inspect fluid level. If there's fluid but nothing happens when you press the button, listen near the engine compartment for a humming sound. No noise? Likely a blown fuse or faulty pump—try replacing the 15A fuse in the driver's footwell fuse box. Hearing the pump but no spray? Clogged nozzles are the usual culprit—clear them with a pin. In winter, don't overlook frozen lines; subzero temps can ice up the system—use half a bottle of winter-grade washer fluid to thaw it. The trickiest issue? Cracked hoses. Pinkish fluid stains under the car mean it's time to replace rubber tubing. If DIY isn't your forte, a shop can handle it for 200-300 yuan.
Last month, my own Jetta also encountered a windshield washer fluid not spraying issue, and I was in a real hurry while driving my kid to cram school. Afterward, I figured it out: first, check the washer fluid level—if it's empty, just refill it; if there's fluid but it's not coming out, clean the nozzle holes by gently poking them with a card pin; if that doesn't work, listen for the pump sound—if there's no sound, open the driver-side fuse box and replace the wiper fuse; if you hear the motor but no fluid comes out, the hose might have come loose, so you'll need to lift the cover under the windshield and reconnect it tightly. In winter when temperatures drop below zero, you must switch to antifreeze washer fluid, or the reservoir could freeze and crack, causing bigger trouble. For regular maintenance, remember to add a dedicated cleaner periodically to reduce the chance of nozzle clogging from scale buildup.
