A malfunctioning windshield wiper system indicates that there is a problem if the wiper motor park position does not return to its resting position.
A weak wiper motor, a filthy windshield, a damaged wiper transmission, improper wiper installation, etc. are some possible causes.
What causes Windshield Wipers Not to Return Rest Position?
There could be an issue with the installation, dirt buildup, or electricity if your front or rear wiper pauses in the middle of the window and does not return to its rest position.
Once you’ve encountered this issue, start by determining its root cause. The following are a few reasons why the windshield wipers are stuck in the up position:
Weak wiper motor
Your car’s wiper system is run by the wiper motor. It controls the motion of the wiper blades and arm. The wiper motor could break down or sustain damage. The wiper movement will be disturbed when it starts to fail, moving slowly at first and then coming to a stop.
Dirty windshield
The wiper mechanism may quickly become clogged with dirt and debris, which would leave the wiper stuck in one spot. The most frequent reason why windshield wipers don’t come to rest is dirt on the windshield.
When dirt builds up, the wiper becomes difficult to operate effectively and will make a squeaky noise. The majority of the time, debris gets lodged in the wiper blades, increasing friction between the wiper and the windshield. The wiper may eventually become stuck in one spot.
Wrongly installed wiper
It can be a badly installed windshield wiper that is acting up and seizing. If the wiper motor, transmission, or relay have been replaced but the wipers are still not operating properly, you might have an alignment problem.
Damaged wiper arms or blades
The wiper’s arm is in charge of maintaining the wiper blades’ position. The arms make sure the wiper stays in place and is aligned correctly while the motor moves it. The wiper arm will no longer be aligned and might not return to its resting position if it is worn out.
Failing intermittent wiper relay
The windshield wiper’s speed is under the intermittent wiper relay’s control. In order to control the wiper motor, it can accomplish this by transmitting a sequence of signals to the wiper module.
Damage to the intermittent wiper relay may alter its speed and result in misaligned windshield wipers.
Damaged wiper transmission
Power from the wiper motor must be transferred to the wiper arm via the wiper gearbox. The wiper movement will be less aligned if the transmission fails.
In situations such as this, you may have a stuck wiper, which prevents the wipers from returning to their rest position. Even with the wiper turned on, it’s possible that it becomes stuck in that position.
Conclusion
Just like any other car system, your wipers may break down. The wiper motor, relay, transmitter, and module make up this system. If any of these parts breaks down, your wiper might not be able to go back to its resting place.
