What is the windshield wiper arm?
The windshield wiper system is made to clear your windshield when it rains, snows, or when dirt and other debris block your view. When you turn on the windshield wiper switch, power goes to the motor and transmission. A linkage connects the transmission of the windshield wipers to the arms of the wipers. The windshield wiper transmission makes the windshield wiper arms move from side to side as they clean the windshield or back window.
For safe driving, especially during inclement weather
, it's important that the wiper arm works well and does its job right. When should I replace the windshield wiper arm on my car?
You should consider getting your windshield wiper arm replaced if it exhibits any of the following symptoms:
Visible damage: If the wiper arm looks broken, cracked, or bent, it may not work right and should be replaced.
Improper/poor cleaning: Even after replacing the windshield wiper blades, if you still see streaks on the windshield, it may be because the wiper arm is not moving or applying pressure properly.
Wiper blade slippage: If the wiper blade keeps slipping or coming off the wiper arm while it's being used, it could mean that the connection mechanism on the wiper arm is worn or broken.
Unusual noises: When the windshield wipers are operating, there is a great deal of chittering or clattering noise—indicating the arm and blade are not properly contacting the windshield.
Age or mileage: Although the wiper arm is designed to last a long time, particularly old cars or those that have been heavily used may show signs of wear in the wiper arm over time.
Wiper arm replacement isn't as common as blade replacement, but it's still necessary if there's obvious damage or the arm isn't cleaning properly.
If you think your wiper arm is worn out, have it checked out by a mechanic the next time you take it in for routine maintenance
. Clear visibility and safe driving in all weather conditions can be promoted through routine wiper system upkeep and prompt repair of any problems. How often should the windshield wiper arm be replaced?
Use, environmental conditions, and routine maintenance all play a role in how long a windshield wiper arm lasts. A wiper arm's expected lifespan is between five and ten years. But it’s always important for wiper arms to be inspected regularly for wear, corrosion, or damage, and replaced as necessary.
Can I replace my windshield wiper arm myself?
