Pontiac Windshield Wiper Arm
Solving the Problems with Your Pontiac Windshield Wiper Arm
Your wiper's cleaning blade isn't a metal part that's similar to a barber's razor. It's actually the long rubber strip that squeaks against the windshield to sweep away water or debris, so you can see the road more clearly. Yet, it will be nothing but a glorified squeegee if it wasn't for your Pontiac windshield wiper arm. It holds the wiper blade and controls its movement so that you don't have to clean the windshield by hand. This is why it's important for you to be aware of any problems caused by a broken wiper arm or two.
The wipers are not cleaning the windshield properly.
Appearances can be deceiving. One or both of your wiper arms might seem undamaged, but when you turn on the wiper switch, they might not be able to clean your windshield properly. Instead, they will just flail about, but in a manner that's different from how normal wipers work. This could be because of a loose nut at the base of each wiper arm. You'll need to remove this nut with your fingers or a pair of needle-nose pliers. Afterwards, put in a replacement part and tighten it into place.
The wipers have been damaged in a collision.
Being in an accident is no laughing matter, even if it's only a small incident. If your Pontiac managed to survive a collision that affected its front, then you should also check the wipers for any damages. If you see that their wiper arms have been bent, then you should check if they could still lie flat against the windshield. If they don't, then their internal springs have been stretched out of shape and they need to be replaced.
The wipers won't work.
If both your Pontiac windshield wiper arms have stopped working, it could be because of a broken fuse. You'll need to locate your vehicle's fuse box and use a fuse puller to take out the fuse for the wipers. If you see that this isn't intact, replace it with a new one and check if it works. If it still doesn't work, then replace the windshield wiper motor as well.
If only one of the arms have stopped working, then it could be because of a faulty connection between the two arms. Open your hood and remove the wiper arms. You'll see as small grille where the linkage that connects the arms to the windshield wiper motor is located. Check if the linkage is still intact, otherwise, you'll need to replace it.
