Whether you purchased new washer fluid jets or are reinstalling the old ones you cleared, the process is the same. You may need to repeat several times and use a couple of piksters for all jets. Best to insert first then turn on the washer as you rotate and remove. Their advantage is they have a brush to dislodge dirt - just keep rotating them in the same direction when you insert and withdraw so you don't leave bristles from the pikster in the jet hole by being too rough - although they are so thin and small the water is likely to clean them out. You insert them through the jet hole where the water comes out - not from the bottom as described above for wire - means no disassembly required and works for jets that have a 90 degree bend in the water supply connection - as in Mazdas.
You can also use teeth flossing piksters - smallest size (0) - you may need to nick the very tip of the wire off to get them to fit in the jet hole as they are ever so slightly bigger at the tip of the piksters for some jets.You can also use a stripped electrical wire.Guitar strings will work well for this because they offer the rigidity needed to pass up through the jet.If the nozzle has multiple openings, you may want to run the wire through multiple times until you clear both holes.
Then run a thin wire through the bottom of the jet, up through the top nozzle. If a pin doesn't penetrate deep enough to clear the clog in the jet, disconnect the hose at the bottom of the jet from beneath the hood. Following that, reconnect the hoses to the pump and run water through the lines to further flush them. Following this, it is a good idea to disconnect the supply hoses from the pump and from the nozzles and blow air through the hoses. Rinse until water runs clear out the fill opening, and soap is gone. Dish soap in the reservoir may also help dislodge dirt and particles. If you suspect that the reservoir is contaminated and may be causing the blockage, it is best to clean it out with fresh water circulating from a hose into the reservoir.X Expert Source Hovig ManouchekianĪuto Repair & Design Specialist Expert Interview. If you do not hear the pump, you can try unplugging the power connector for the washer fluid pump and check voltage at the connector, if the voltage is present when trying to activate pump then pump probably needs to be replaced.If you are unsure if the pump is on, ask a friend to listen from outside the vehicle near the hood.In very cold weather, check for ice in washer fluid tank, you can try to use a warm hair dryer to defrost washer fluid pump and tank or spray windshield de-icer into washer fluid tank. If the jets are clogged, you will hear the pump despite no fluid spraying. Before attempting to unclog the washer fluid jets, turn them on and listen for the low hum of the washer fluid pump.
