Acura ZDX Windshield Washer Nozzle Replacement Cost

The windshield washer nozzles are supposed to last the lifetime of a vehicle. Unfortunately, many do not. If the washer solvent is not kept clean, the washer nozzles can clog. But the real reason many nozzles fail is that they become brittle over time. The nozzles are often made from black plastic. These plastic parts mounted on top of the hood are exposed to the sun year round. They heat up, dry out, become brittle, and often break. How long they last really depends on the particular manufacturer.

To determine if a washer nozzle is at fault when the washers do not work, a technician will first rule out other probable causes, such as the washer motor. If the motor can be heard operating when the switch is activated, the technician will check for leaks in the hoses. This can be done by disconnecting the hoses from the washer nozzles and testing the washers. If solvent comes out of the hoses (but did not come out of the nozzle(s), the washer nozzle(s) are clogged. Diagnosis of the heating element on a washer nozzle involves disconnecting the wiring harness plug to the nozzle and testing the element with a multimeter.

To replace a windshield washer nozzle on most vehicles, a technician will open the hood and remove or set back the hood insulation by removing the clips that hold it in place. With the insulation out of the way, the technician will pull the rubber hose off of the nozzle and unplug the wire harness connector (if so equipped). The retaining tabs are gently squeezed to release the nozzle from its mounting hole and the nozzle is pulled out through the top of the hood. A new nozzle is set in the hole and snapped into place. The rubber hose is attached and any wiring is plugged back in before the hood is closed and the nozzle is tested. It may be necessary for the technician to aim the nozzle(s) before the vehicle is put back into service.

Care should be exercised when removing a washer nozzle from the hood. It is possible to damage the sheet metal and the protective paint coatings when attempting to squeeze the release tabs. The nozzle should not be twisted or forced out of the hood. On the contrary, it should release gently.

Because the washer nozzles can become very brittle and break easily, extreme care should be taken any time work is done near the back of the nozzles or solvent hoses.

Depending on the placement of and access to the windshield washer nozzles on a given vehicle, replacement can usually be done by someone with an intermediate level of DIY experience. The nozzles are often tricky to release from the hood and damage to the sheet metal or paint coatings is possible.
