How should a technician check for proper operation in a faulty windshield washer system?

When diagnosing a faulty windshield washer system, evaluating hose integrity is essential because the hoses are responsible for transporting washer fluid from the reservoir to the nozzles. If the hoses are damaged, clogged, or have leaks, the washer fluid may not reach the nozzles, resulting in system malfunction. A technician must check for any physical damage or blockages in the hoses to ensure that the fluid can flow freely and that the system operates correctly.

While inspecting the fuse is a relevant step in checking electrical components, it does not address mechanical issues in the system. Similarly, checking the pump voltage helps understand if the pump is receiving power, but it does not confirm if the fluid can be delivered due to hose problems. Examining fluid levels is important, but if the hoses are compromised, the presence of fluid alone will not guarantee that the system is functional. Thus, ensuring the integrity of the hoses is a crucial part of troubleshooting a windshield washer system.
