A washer pump in a car's windshield wiping system moves washer fluid from a reservoir through hoses. The motorized pump pressurizes the fluid to allow it to be squirted from the hoses through nozzles onto the front and/or rear windshield of a car. The washer fluid helps windshield wipers get rid of rain, dirt, or other objects that can interfere with a driver's visibility. If your washer fluid is not being sent out when activated, the solution could simply be filling the washer system's reservoir with more fluid or cleaning the nozzles and hoses. In more severe cases, the washer pump may need to be replaced. Here are steps to troubleshoot a windshield-washer pump.
Open the hood and listen when some helper operated the "squirters". You should hear a high-pitch whine that the washer pump makes. No noise? Bad pump or bad wiring or corrosion at the terminals of the pump. Noise heard? Hoses are plugged up.OR the hose fell off the bottle and the bottle is empty. You can use a small wire from a wire brush to un plug the squirt nozzles on the hood.Use pliers to feed the wire into the nozzles-you may poke your finger(sharp!). Un plug the hoses that lead to the hood and apply air pressure to the hose from the windshield washer bottle. Washer fluid is not toxic in small doses.
Yes there are two pumps located in the wiper fluid reservoir. If your in a bind, you can switch the plugs and small hose that go to them because they are both the same. The upper pump operates the back, and the lower pump operates the front. The back won't work until it gets replaced, but it beats driving backwards.
Check the hoses running to the front windshield washer nozzles. If the hoses are good check the pump to see if it is working correctly. Remove one of the hoses from the spray nozzle and see if the pump is working. If it is then the spay nozzles are stopped up. Use a needle to clean them out. They can easily get plugged with wax. If the pump is not working then either the fuse is blown or the pump is defective.
check that the jet is not clogged.take a very thin piece of wire,like from a twist tie and clean the hole. maybe the hose is pinched or disconnected.if you spray the rear,you should hear the pump working.i have seen hoses come off and if you spray for 20 seconds,it may leak from the car
