Volvo 850 Wiper Arm
Troubleshooting Common Problems of Volvo 850 Wiper Arm
We often give very little importance to small things such as the wiper arms until we need them-and they don't properly work. Needless to say, unless you want to drive blind through the snow or torrential rain because your wiper arms fail to work, you should know what to do in case they fail. No, you don't pull over and call 911. There's a better, manly approach than that.
One wiper arm is slower than the other
It doesn't matter which side is small, wipers aren't designed to work that way. First determine which one is moving slower (or not at all). In most cases, the cause is a loose connection. If the wiper doesn't move, something is broken or rusted in the wiper arm. Remove the wiper arm to examine the connection. Tighten any loose part or replace rusted or broken part.
Wipers don't move at all
First check the bolts holding the wiper arm. If both bolts are not turning back and forth, it is definitely not the connection. If the wiper only clicks, there is definitely something loose in the wiper motor. Locate the motor and fix the problem. If something is broken and could not be fixed, or if the motor doesn't turn, replace the wiper motor.
Wiper blades stay good for at least 1 year. After that, they need to be replaced, especially if they smear water. But if you notice smearing even if the blades are relatively new, replace your windshield wiper fluid or clean your wiper and windshield. If the smearing persists, replace the wiper blades. Pull over to the side of the road if windshield smearing already affects your visibility. At 65 mph, you are covering 96 feet of ground and that's quite a lot. Don't risk it. After all, the solution is very simple.
If smearing only appears on one side, it is probably the cold weather and there's not much you can do about it. But if the weather is not cold and there's still smearing, you have to replace your wiper blade.Wiper arms are shaking
No, the problem isn't the blades. Open the plastic cover of the wiper arm to access the bolts. Tighten it down and your problem is solved.
