Check the washer hose from the beak and take it back to the tank after lifting the hood. You may also come across a plastic spiked adapter or a directional check valve. Try dislodging the tubing and check if the washer is working again. If the fluid in the tiny amount is spewing, then nozzles are impassable. You need to take out the piece and clean it properly by inserting the pin and making space for the dust and particles to come out. Push pressure to blow the blockage down towards the pipe and out at the dislodged and disconnected end.

Once pressure has been applied, check for the power. Suppose the fuse is perfectly operational, but the pump is unable to perform. In that case, you need to disengage the connector at the pump and identify strongly with the help of a voltmeter. Once the washer switch has been turned on, it should ideally be located at 12 V. If you cannot listen to the pump’s sound and the fuse working well, then the fault is likely because of an inefficient electric connection at the pump. It may even be because of a faulty pump.

Afterward, try removing the pump wire connector and take help from another set of hands to operate the pump switch. This would help you check the power at precisely 12 volts using a digital meter located at the connector. If there is no voltage detected, then the washer switch or the wiring are equipped with problems. This indicates another set of issues within the vehicle that needs proper mechanical attention. If the voltage is identified and detected, you need to coat the terminals after cleaning them with the help of the dielectric silicone grease.
