Overview & Operating Principle
▲
The NOZZLE WASHER is the windscreen washer nozzle — a precision-formed plastic or brass jet body mounted in the bonnet panel, scuttle cowl, or wiper arm that receives pressurised washer fluid from the electric washer pump and directs it as a calibrated spray pattern onto the windscreen surface to pre-wet the glass ahead of the wiper blade sweep. The nozzle body contains a precisely sized orifice — typically 0.3–0.8 mm diameter — that converts the pump's volume flow into a pressurised jet; a ball-and-socket or adjustable jet element whose angular position is set during vehicle assembly to direct the spray to the correct zone of the windscreen relative to the wiper's swept arc; and a one-way check valve in most designs that retains fluid in the nozzle body between wash cycles, allowing the spray to begin immediately when the washer is activated without the pump first having to overcome an empty nozzle. On heated nozzle designs an electrical resistance heating element is integrated into the nozzle body to prevent washer fluid from freezing in the orifice in cold weather — a non-heated nozzle that freezes in winter produces zero fluid delivery to the windscreen until the nozzle is manually thawed. Modern fan-spray nozzle designs replace the traditional pin-hole jet with a flat fan orifice that distributes fluid across the full width of the wiper's swept arc in a single broad spray rather than requiring two separate pin-hole jets to cover the driver and passenger halves of the screen.
This unit — CHRYSLER 55079049AA — is manufactured to OEM-equivalent specifications: nozzle body outer diameter and bonnet panel mounting clip geometry, jet orifice size and spray pattern angle, ball-socket or adjustable jet range, check valve retention pressure, heated element voltage and wattage where applicable, and fluid pipe connection push-fit or barb diameter are matched to the original part. Supplied as a direct replacement for standard fitment. Available wholesale from 0.29 USD, MOQ 100 pcs, production lead time 67 days.
Windscreen washer nozzles fail through orifice blockage from mineral scale deposits from hard water in the washer fluid, from washer fluid additive crystallisation when the fluid concentration changes with evaporation, and from fine debris particles that pass the washer reservoir filter; through jet angle shifting after a bonnet impact or from UV embrittlement of the ball-socket retaining material that allows the jet to drop to an incorrect angle; through check valve failure that allows the fluid line to drain back to the reservoir between wash cycles, producing a delay of several pump cycles before fluid reaches the screen; and through body cracking from thermal cycling in extreme climate environments.
Symptoms & Diagnostics
▲
No fluid delivery from one nozzle while the opposite nozzle sprays correctly and pump operation is confirmed — the non-delivering nozzle is blocked; confirm by disconnecting the fluid pipe from the blocked nozzle and activating the washer — if fluid flows freely from the pipe, the nozzle orifice is blocked; if no fluid flows from the pipe, the blockage is in the line or the pipe junction; a blocked orifice can sometimes be cleared by inserting a fine pin of the correct diameter — typically 0.4–0.6 mm — to dislodge the deposit without enlarging the orifice.
Fluid spraying to the wrong position — hitting the A-pillar, the bonnet edge, or the base of the windscreen rather than the wiper swept area — the ball-socket jet has shifted from its factory-set position; this typically occurs after a bonnet impact, a car wash brush contact, or from UV embrittlement of the ball-socket retaining clip; the jet angle can be reset using a fine needle or pin to reposition the ball within the socket to the correct spray target position without removing the nozzle from the bonnet.
Delay of several seconds before washer fluid appears on the windscreen after the washer stalk is operated — pump noise confirmed immediately — the nozzle's check valve has failed open, allowing the fluid line to drain back to the reservoir between wash cycles; the pump must refill the empty line before fluid reaches the nozzle on the next activation; a delay of more than 2 seconds on first operation from a warm start confirms a failed check valve.
Fluid delivery only in freezing weather after the vehicle has warmed up — nozzle confirmed unblocked and pump confirmed operational in warm conditions — the non-heated nozzle's orifice is freezing during cold weather despite washer fluid of the correct concentration; confirm the washer fluid concentration with a refractometer — a correctly concentrated fluid does not freeze at ambient temperature; if the concentration is correct, the nozzle's orifice geometry may be trapping a small water droplet that freezes independently of the bulk fluid concentration.
Continuous dripping from one nozzle after the washer pump stops — fluid continues to drip onto the bonnet or windscreen for several seconds after the wash cycle ends — the check valve is stuck partially open, allowing the pressurised line to drain slowly through the nozzle after pump pressure ceases; the drip is not a pump fault — it is a nozzle check valve fault; disconnecting the nozzle and temporarily capping the pipe line confirms whether the drip stops, confirming the valve is in the nozzle rather than the pump.
Washer nozzle body cracked or missing from the bonnet aperture — the nozzle has been dislodged by a car wash brush, bonnet impact, or frost heave — a missing nozzle delivers fluid onto the bonnet surface rather than the windscreen, wasting washer fluid and potentially introducing fluid to the engine compartment; the bonnet aperture may also allow water ingress to the wiper motor and linkage area if the nozzle is absent for an extended period.

Installation Tips
▲
- Before replacing a blocked nozzle, attempt to clear the blockage with a fine pin or compressed air — a blocked orifice from mineral scale or debris can frequently be cleared without replacing the nozzle; insert a fine pin of the correct diameter into the orifice and gently rotate to dislodge the deposit without enlarging the hole; follow by directing compressed air into the nozzle from the fluid line side to blow the dislodged deposit through the orifice; test the spray pattern before removing the nozzle from the bonnet.
- Remove the old nozzle from the bonnet panel using a trim removal tool inserted into the underside of the bonnet aperture — the nozzle body is retained by one or two spring clips that engage the underside of the bonnet panel; inserting a flat trim tool between the nozzle body and the bonnet surface and pressing the retaining clips inward while pushing the nozzle up through the aperture releases the nozzle without damaging the bonnet paintwork; never pull the nozzle upward from the bonnet surface without releasing the retaining clips as this scratches the paint around the aperture.
- Disconnect the fluid pipe from the old nozzle before pushing the new nozzle into the aperture — the pipe push-fit or barb connection is easier to access with the nozzle partially or fully removed from the bonnet; confirm the pipe's push-fit connector engages the new nozzle's barb with an audible click; a pipe that is not fully engaged will pull off the nozzle under pump pressure on the first activation, draining washer fluid into the bonnet cavity.
- Set the new nozzle's spray angle before closing the bonnet — with the nozzle installed and the fluid pipe connected, activate the washer pump and observe where the jet strikes the windscreen; the correct target zone for each nozzle is the centre of the wiper swept arc on the respective side of the screen; adjust the ball-socket angle using a fine pin inserted into the jet orifice to reposition the ball in its socket until the spray hits the correct zone; make small incremental adjustments and retest after each adjustment.
- On heated nozzle designs, confirm the electrical connector is fully engaged and the heating circuit is functional — connect the electrical connector before testing the spray angle to confirm the heating element illuminates the indicator on the heated rear screen switch where applicable; a heated nozzle with a disconnected or faulty heating element will freeze in cold weather regardless of washer fluid concentration.
- Install the new NOZZLE WASHER (CHRYSLER 55079049AA), activate the washer three times in succession and confirm fluid delivery begins within 1 second on the first activation (check valve functional), the spray pattern covers the correct zone of the wiper's swept arc, and no fluid drips from the nozzle for more than 2 seconds after the pump stops before returning the vehicle to service.
Tools: flat trim removal tool for clip release, fine pin (0.4–0.6 mm) for orifice clearing and jet angle adjustment, compressed air for blockage clearing, multimeter for heated nozzle element resistance check.
Frequently Asked Questions
▲
Should both washer nozzles always be replaced simultaneously when one is blocked or damaged?
Replacing both nozzles simultaneously is recommended when one has failed from mineral scale blockage — both nozzles receive the same washer fluid from the same reservoir and accumulate the same scale deposits from the same hard water source; if one is blocked, the other has the same scale accumulation and will block within a short interval. When one nozzle has failed from physical damage — a bonnet impact or car wash damage — only the damaged nozzle requires replacement. ok.parts supplies washer nozzles individually and in matched pairs at wholesale MOQ from 0.29 USD per unit.
What causes repeated washer nozzle blockage from mineral scale and how can it be prevented?
Mineral scale blockage results from using tap water in the washer reservoir without adequate washer fluid concentrate — the water's dissolved calcium and magnesium salts are concentrated by evaporation at the nozzle orifice between wash cycles and eventually crystallise to block the orifice. Prevention requires filling the reservoir only with commercial washer fluid concentrate diluted to the correct concentration with distilled or softened water rather than tap water, particularly in hard water regions. A concentration of 1:3 washer fluid to water (summer mix) provides adequate cleaning and prevents scale formation; in areas with very hard tap water, using a 1:1 mix or bottled water for dilution eliminates scale deposition entirely. Commercial washer fluid concentrates contain surfactants that dissolve scale deposits and inhibit crystal formation at the orifice.

Frequently Replaced Together
▲
| Part | Reason for Combined Replacement |
|---|---|
| Washer Pump OEM ref. varies — front, rear, or headlamp washer | A washer pump that is producing abnormally low pressure — delivering fluid to the nozzles as a weak dribble rather than a pressurised jet — will not provide adequate washing performance even with new clean nozzles. If replacing blocked nozzles does not restore the correct pressurised spray pattern, measure pump output pressure at the nozzle pipe connection; a pump delivering below 0.8 bar at the rated voltage requires replacement simultaneously with the nozzles to restore the complete washer system to correct specification. |
| Washer Fluid Reservoir OEM ref. varies by vehicle | A cracked washer reservoir that has been losing fluid slowly may have allowed the fluid level to drop below the pump inlet, causing the pump to run dry and accelerating impeller wear. If the reservoir shows hairline cracks or the fluid level drops faster than the nozzle output can account for, replace the reservoir simultaneously with the nozzles — a cracked reservoir will continue to leak regardless of nozzle condition. |
| Wiper Blades Driver and passenger — OEM length per vehicle | Nozzle replacement provides the standard opportunity to inspect and replace the wiper blades simultaneously — a nozzle that has been blocked for an extended period has caused the wiper blades to sweep dry glass, accelerating rubber edge wear through friction and heat. Fitting new blades alongside new nozzles ensures the complete washer-and-wiper system operates as a matched new assembly from the first use. |
