However, you *can* adjust the *speed* and *pattern* of the wipers. This is usually done through controls inside the vehicle. These controls allow you to select between different speeds (low, medium, high, intermittent) and sometimes different wiping patterns (like a single sweep vs. a more comprehensive back-and-forth pattern). Some newer vehicles even have rain-sensing wipers that automatically adjust the speed based on the amount of rainfall.
If you're experiencing problems with your wipers not covering the entire windshield, the issue likely lies with:
* Worn-out wiper blades: Replace them. This is the most common cause of inadequate windshield coverage.
* Wiper arm misalignment: The arm might be slightly out of position, preventing full contact with the glass. This usually requires minor adjustment, and sometimes professional help.
* Mechanical failure in the wiper mechanism: This could involve a faulty motor, linkage problems, or other internal issues, requiring professional repair.
So, in short, you can adjust the *operation* of your wipers, but not their physical range of motion unless you replace parts.
