  • Always make sure your windscreen wipers are in good condition. Worn wipers can prevent visibility and increase the likelihood of an accident. 
  • Do not only depend on the rain sensor to turn on the wipers. Rain sensors can malfunction. Operate the windshield wipers manually if necessary. 
  • It is not recommended to use water repellent coating on the windshield. Increased daze is possible which can reduce visibility in low light, light rain or at night. 
  • In case of freezing temperatures, check that the wipers are not stuck or frozen to the glass. Turning on the wipers can cause damage to the wiper motor or blow the wiper fuse. 
  • Always turn off the wiper switch on the steering column to off or 0 before entering an automatic car wash. This will prevent the wipers from turning on while the car is driven through the car wash. 
  • Worn wiper blades can cause smearing of the glass which can reduce visibility and functionality of the rain sensor. 

Windshield washer fluid not working

Let's say you added windshield washer fluid to your car but the washer fluid is not working. You press the swtich on the steering column but no water sprays out. Here are a few things you need to check. 

Washer fluid leaks

If the windshield washer fluid on your car is cracked, it will leak the fluid. In most cases, the fluid starts to drip as soon as you add washer fluid. Move your car to a new dry location and pay attention for washer fluid leaks. Leaks can also develop at the hoses that transfer the washer fluid to the windshield. Another common place where leaks can develop is where the windshield motor connect to the windshield washer reservoir. This is a common problem if you don't use windshield washer fluid but use just water. The water will freeze and either crack the reservoir or the delivery lines. 

Bad windshield washer motor

If you press the washer fluid switch and you hear no noise coming from the washer reservoir the motor may be burned out. Try pressing the washer switch when the engine is turned off but ignition is on. Have a helper listen carefully for a small motor to engage near the windshield washer fluid reservoir. 

Blown Fuse

wipers don't spray water

If you don't hear the motor working, it could be a blown fuse. Locate the fuse box on your car. If you don't know where they are, look them up in the owners manual. Find which fuse protects the windshield washer fluid circuit. Remove that fuse and make sure it is not blown. 

The following video shows you how to check for a blown fuse.
