How this system works:
Your windshield wiper system is actually far simpler than you may think, with only a handful of parts. Power to the system comes through wiring and is regulated by a fuse, causing the wiper motor to rotate when the switch is engaged. This rotation is converted to a back-and-forth movement by a linked system of arms connected by a pivot point or stud. At the end of the line lies the wiper blade. If any part of this system breaks, it can cause your wipers to stop working.
Common reasons for this to happen:
- Broken windshield wiper controls: The switch you use to operate the wiper motor gets a lot of use and can fail internally causing a break in power between the wiper controls and the wiper motor. Such a failure will prevent the windshield wipers from operating.
- Blown fuse: If the fuse for your wipers blows, then no power can go to your windshield wiper system. When a blown fuse is responsible for your wipers not working, you will not hear anything when you turn them on, nor will the wipers move. Instead of pulling fuses out left and right trying to determine if a fuse has blown, enlist a mechanic to check them for you, or else you may accidentally cut power to other pivotal systems.
- Faulty motor: A problem with the wiper system motor can cause the wipers to quit functioning as well. In this case, you may or may not hear a noise when you turn the wipers on from the switch. If the motor is starting to go out, you could hear it laboring to work, but there will be no noise at all if the motor has gone out completely. Since you must remove the wipers in order to reach the motor, leave checking this issue to a trained technician to prevent causing further damage.
- Bad arm or pivot point: With wear and tear, the mechanical parts of your wiper system can break. If this happens, you will likely hear the motor running when you turn on your wiper switch, although the wipers won’t be able to move properly. Since there are only a few components of your wiper system, it won’t take long for a mechanic to discover which of the mechanical parts is in need of replacement.
What to expect:
A top-rated mobile mechanic will come to your home or office to determine why your windshield wipers are not working. The diagnosis will include checking your fuses and other components of the windshield wiper system in your vehicle.
After the inspection, the mechanic will provide a detailed report that describes the source and cause of the issue preventing the wipers from operating properly, along with the scope and cost of the necessary repairs.
How important is this service?
Although no one will be the wiser about your windshield wiper issues when the weather is nice, the consequences can be disastrous once rain or snow begins to fall. The poor visibility caused by a non-working wiper system presents a grave safety issue to yourself, any passengers with you, and others on the road. Have the problem diagnosed and fixed at the earliest opportunity because inclement weather can occur at any time.
