What is the reason for the windshield washer motor not making noise and the wipers moving in winter?

The reasons for the windshield washer motor not making noise and the wipers moving in winter are: 1. The windshield washer fluid level is too low; 2. The spray nozzle is blocked by dust. The function of the car generator is: when the engine is running normally, it supplies power to all electrical equipment except the starter motor, and at the same time charges the battery. The maintenance methods for the car generator are: 1. Clean the accumulated dirt and dust on the surface of the generator; 2. Check and adjust the tension of the drive belt; 3. Check whether the wiring between the generator and the regulator is firmly connected. The steps for replacing the generator are: 1. Disconnect the battery cable; 2. Locate the alternator; 3. Unscrew the bolts and loosen the belt that fixes the generator; 4. Remove the alternator, unplug and remove all nuts connecting the electrical components; 5. Install the new generator by reversing the process.
I've encountered this issue before. In winter, the washer fluid won't spray, the motor makes no sound, but the wipers still work. It's most likely that the washer fluid is frozen, causing the washer pump to jam, while the wiper motor operates independently. First, check if the reservoir and pipes are frozen. Using regular tap water or low-freezing-point washer fluid in cold weather can cause this. Then, inspect the washer pump's fuse, which might have blown, or the motor itself could be faulty. Safety first—don't force the switch, as it could burn out the motor. Park the car in a warm garage to let it thaw, or carefully use a hairdryer to heat the system. Afterward, switch to dedicated winter antifreeze washer fluid—don't skimp on this, as poor visibility on the road is dangerous. I learned this the hard way, so now I check and maintain it every year before winter.
