Having windshield wiper/washer problems? Here are some more common problems.

  • Motor:
The wiper motor is commonly replaced and was often not the problem. Don't replace the motor yet. maybe it's not the motor. It could be a fuse or something at the wiper switch. The wiper motor has two windings, fast and slow. The wiper switch sends a ground signal to each motor winding. More often, there are problems with the relay, or at the wiper switch, or in the cable to the motor.
  • Windshield Washer:
Don't be too quick to replace the washer pump. The problem is often just a clog in the sprayer heads. You can clean out the sprayer holes with a needle, some have two holes, so look closely. Hope this helps.

SOURCE: rain sensor wipers willnot work or spray washer

Either the switch is bad or most likely the motor is bad. Even though it works on high, the motor can still be bad.

Where is the fuse for the water pump for the window washer


A washer pump in a car's windshield wiping system moves washer fluid from a reservoir through hoses. The motorized pump pressurizes the fluid to allow it to be squirted from the hoses through nozzles onto the front and/or rear windshield of a car. The washer fluid helps windshield wipers get rid of rain, dirt, or other objects that can interfere with a driver's visibility. If your washer fluid is not being sent out when activated, the solution could simply be filling the washer system's reservoir with more fluid or cleaning the nozzles and hoses. In more severe cases, the washer pump may need to be replaced. Here are steps to troubleshoot a windshield-washer pump.

Where can I purchase fuse #45 for my chevrolet equinox lt 2007 in richmond, va


It sounds as if the windshield washer pump, located at the base of the windshield washer fluid reservoir, has lost it's seal. When this occurs, washer fluid seeps into the pump and shorts it out. I advise that you remove the pump to confirm this before replacing the fuse. A replacement wind washer pump and fuse can be found at your dealer, local auto parts store or the internet (Rockauto.com has always been a great source for quality parts at a very competitive price and I use them all the time). Hope this helps.

Windshield washer doesn't pump fluid, dealer says I need new wiper rain sensor


If you want to bypass it, I suggest you run a couple of wires from the battery, via a switch, directly to the washer motor. To verify what the dealer has told you, take it to another dealer or independent repair shop and get them to diagnose the problem.

92 ford escort lx front windshield washer fluid pump


The switch or wire is damaged, or possibly the ground wire to the pump is loose. Che k to see if one of the terminals in the pump connector has 12 volts while someone turns the key on and tries ti pump fluid. If yes, your problem is the ground wire. If no, you will have to check the switch.

Windshield Wipers won't spray 2004 Rav4


I think the dealer is mistaken, the is a washer jar for the front and one for the rear. be sure fluid is pure, and undiluted. clean out front washer jar, if it has been contaminated with any wrong fluid it will never flush it self out. Second point is front washer pump may have minor seal concern that is only apparent when cold. if first step does not cure, I would recommend repalcing pump. Keep me posted
