What is the reason why the Jetta wiper spray wiper motor does not move?
3 Answers
Jetta wiper spray wiper motor does not move for the following reasons: Dislocated transmission linkage: It may be due to incorrect connection of the transmission linkage to the wiper arm. Some arms are fixed to the rocker arm with screws, which might be locked and thus unable to move. Blown fuse: The wiper may not move because the fuse (to prevent circuit overload) has blown, causing the wiper to malfunction. In this case, you need to open the fuse box and check whether the corresponding fuse (refer to the manual on the cover) is blown. If it is, simply replace it, but remember to turn off all the car's electrical switches before replacement.
When I encounter the issue of the Jetta's wiper washer motor not working, there are usually a few common culprits. The most likely is a blown fuse, located in the engine compartment's fuse box—you'll need to identify and replace the one related to the wipers. The wiper motor itself might be aging and unable to turn, as prolonged use can wear out the carbon brushes inside or cause water damage. A malfunctioning switch or control unit could also be the reason, where the motor fails to respond after the washer is activated. Additionally, poor wiring connections or short circuits are not uncommon, such as loose plugs or corroded wires. A faulty relay can halt the entire system, and while checking it isn’t complicated, it requires attention to detail. I recommend starting with the fuse—it’s a quick and easy way to rule out basic issues. If that doesn’t solve it, visit a professional shop for inspection. Driving without functioning wipers is too risky.
My old Jetta also had an issue where the wiper motor wouldn't start after spraying water, and here's how I solved it. That time, the wipers completely stopped working. First, I checked the fuse and found it was fine. Later, I discovered that the relay contacts were burnt, and cleaning them improved the situation. It could also be that the motor was stuck; after years of use, internal rust or bearing failure might require replacement. Short circuits or open circuits in the wiring are also common causes of failure. When the wipers spray water, the current is high, and instantaneous overloads that blow the fuse are more frequent. I find it quite unsettling to encounter this while driving, especially in rain or snow when visibility is poor and the road is hard to see. So now, I regularly check the wiper system to avoid sudden problems. Remember, safety comes first—don't attempt repairs yourself. It's more reliable to get a diagnosis at a proper repair shop.
