Usual Indications of Problems with the Toyota Land Cruiser Windshield Wiper Arm
The windshield wiper arm holds the wiper blade on one side and pivots from the wiper motor on the other. Without the wiper arm, the windshield would not move at all because the wiping motion is not transferred from the wiper motor. Since the windshield wiper arm is located in front of the windshield, it is exposed to a lot of damaging elements. Following are some signs that the Toyota Land Cruiser wiper arm is taking its toll from these elements:
One wiper moving slower than the other
Your wipers are supposed to move in unison or with the same speed. If you notice that one is moving slower than the other, there may be an issue with the windshield wiper arm. This problem is usually caused by the retaining nut that holds the base of the wiper arm. The retaining nut is located at the bottom of the windshield, exposing it to different elements that can make it loose. To solve the problem, you can take out your adjustable wrench and tighten the retaining nut.
Wiper does not move
Loss of wiping motion is a more serious issue of a loose retaining nut. If you experience this problem, your retaining nut may be very loose to the point that it does not hold the wiper arm at all. That being said, you need to check the retaining nut of the problematic windshield wiper arm. It may be very loose or has actually gone missing already. You need to tighten it with a wrench or replace it before hitting the road again.
Stuck Toyota Land Cruiser windshield wiper arm
There would be instances when you need to remove the wiper arm even though you are not going to replace it. If you are having a difficulty taking it out, there is an obvious issue with its base that connects to the retaining nut. Because of its exposure to water and moisture, the wiper arm mayrust. When rust develops on the base of the windshield wiper arm, it can stick to the retaining bolt and make it hard to remove.
