Too little water is coming out of the windscreen washer jets. What can cause this?

Your answer is correct because both partly blocked jets and a defective washer pump can cause too little water to come out of the windscreen washer jets. If the jets are clogged with dirt or debris, the water flow is restricted. Similarly, if the washer pump is faulty, it cannot push enough water through the system. However, having too much water in the reservoir does not reduce the amount of water sprayed; the system is designed to handle the reservoir's capacity. This understanding helps you identify common mechanical or maintenance issues affecting the washer function.
