Why is the windshield washer fluid not spraying when the reservoir is full?

[AndrewFitz]

Here are the common reasons why the windshield washer fluid does not spray despite a full reservoir: 1. The washer nozzle is clogged, or there is a blockage or leakage in the washer fluid supply line. If the washer nozzle is clogged, you can use a needle or thin wire to unclog it. If the washer fluid supply line or nozzle is damaged, it is recommended to have it inspected and repaired at a service center. 2. The windshield washer fluid is frozen due to insufficient freezing point. If the ambient temperature is low, the washer fluid level is normal, and the motor is operational, the solution is to replace the washer fluid with one that has an appropriate freezing point. 3. The washer motor fuse is damaged, or the washer motor or wiper switch is faulty. If the motor does not operate when attempting to spray, it is necessary to have it inspected and repaired at a service center.
