Why Volkswagen Tiguan Windshield Wiper Fluid Not Working

Reasons Why Volkswagen Tiguan Windshield Wiper Fluid Not Working

Low windshield wiper fluid level:
The most common reason for windshield wiper fluid not working is that the fluid level is too low. To check the fluid level, open the hood and look for the windshield wiper fluid reservoir. It is usually a clear plastic container with a blue cap. The fluid level should be between the full and low marks. If the fluid level is low, add more fluid to the reservoir.

Defective windshield wiper fluid pump:
The windshield wiper fluid pump is responsible for pumping fluid to the windshield wipers. If the pump is defective, it will not be able to pump fluid to the wipers, and the wipers will not work. To check the pump, turn on the windshield wipers and listen for the pump to run. If you do not hear the pump running, the pump is likely defective and will need to be replaced.

Clogged windshield wiper fluid nozzle:
The windshield wiper fluid nozzles are responsible for spraying fluid onto the windshield. If the nozzles are clogged, they will not be able to spray fluid, and the wipers will not work. To check the nozzles, turn on the windshield wipers and look at the nozzles. If the nozzles are clogged, you can try to clean them with a toothpick or a needle. If the nozzles are still clogged, they will need to be replaced.

Faulty wiring or electrical connection:
The windshield wiper fluid system is controlled by a switch on the dashboard. The switch sends a signal to the windshield wiper fluid pump, which then pumps fluid to the nozzles. If there is a problem with the wiring or electrical connection, the switch may not be able to send a signal to the pump, and the wipers will not work. To check the wiring, use a voltmeter to check for voltage at the pump connector. If there is no voltage, the wiring or connection is faulty and will need to be repaired or replaced.

Air in the windshield wiper fluid system:
If there is air in the windshield wiper fluid system, it can cause the wipers to not work properly. To check for air in the system, turn on the windshield wipers and look at the nozzles. If the fluid is coming out in a stream, there is no air in the system. If the fluid is coming out in a spray, there is air in the system and it will need to be bled.
