What is causing only a weak stream of fluid to come from the windshield washer spray nozzles?
The first thing to inspect is the spray nozzle itself. Carefully use a safety pin to clear the nozzle end. If that doesn’t work, inspect the hoses that go from the windshield washer fluid reservoir to the spray nozzles. Look for kinks or holes that may reduce flow. If you don’t have any luck with that, you should disconnect the supply hose from the reservoir and blow compressed air through it. This should clear the hoses and nozzles of any dirt, debris, or scaling. Be sure not to be in the pathway of the spray nozzles. Wear eye protection to protect yourself from particles that may be dislodged due by the compressed air. If the hoses and nozzles seem clear, then you may need a new washer pump.
