Water streaks, dirt stains, and mud splashes on the windshield can spell a lot of trouble for the driver. Without a clear view of the road ahead, it's much easier for the driver to miss a spot, make a wrong turn, or miscalculate the distance. Imagine this happening when it's raining hard, it's snowing everywhere, or there's hardly enough light from the street. This can end badly.in a low-speed collision or a tragic vehicular accident.
If your wipers aren't doing a great job at sweeping specks of dirt and water residue off the glass, don't let this go on for long. If it's the wiper arm that's causing the problem, here's what you can do:
What should be done when wiper arms are bent?
If the wiper arms seem bent, what you can do is try to straighten them out first. Be careful not to break the arms or twist them out of shape. Make sure that each wiper arm is fixed to the right angle. To test the repaired wiper arms, switch on the wipers to see if the arms have been properly adjusted, such that the blades can easily push dirt and water off the surface. If the wiper arms can't be brought back to the same configuration or condition as before, it's better if you replace them.
What could be the best repair solution to a loose wiper arm?
If the blades are fine yet the wipers can't seem to clean the glass evenly and thoroughly, the problem can be a loose wiper arm. To check, you have to inspect both arms to find which one appears to be loose. You can also just turn on the wipers to see which side of the glass isn't getting the right amount of cleaning. The loose arm can be fixed by tightening the nut located at the arm's base. If the nut is rusted or broken, you have to use a new one.
What could be the problem when only one wiper arm is working?
If only one wiper arm is moving, then what you have to do is check the linkage. You have to pull out the wiper arms from under the hood. Beneath the grille, you'll find a linkage connecting the motor to both wiper arms. Reconnect the linkage in case this has been detached. If the linkage appears broken, you have to remove this. Buy a new linkage to restore the connection between the motor and the arms. Once the new linkage has been attached, test the wipers to see if both wiper arms are now moving.
What should be checked in case both wiper arms aren't working?
If both wiper arms won't move when you turn on the wipers, you'll have to inspect a couple of things. Start with the fuses. Using the vehicle manual, trace where the fuses are and what they control. Remove the fuse using a fuse puller to check for any sign of damage. The broken fuse should be replaced to fix the wiper arm problem. If everything looks fine with the fuse, you may be dealing with a malfunctioning wiper motor. To remove the defective motor, you have to unplug the negative battery from the terminals. The leads from the sides of the motor should also be disconnected. After unscrewing the bolts of the motor, you can put in a new one by reconnecting and reinstalling everything you've removed.
