Wiper Not Moving at All
So, your wiper is giving you the silent treatment? Let’s tackle this head-on:
- Check the wiper switch: Sometimes, the switch itself might be the culprit. Ensure it’s not stuck or damaged.
- Inspect the wiper motor: If the motor seems lifeless, it could be the source of the issue. Look for any visible damage or signs of wear.
- Test the power supply: Grab a multimeter and check if the motor is getting the power it needs. No power, no movement!
Wiper Moving Sporadically
Is your rear wiper throwing a tantrum with its sporadic movements? Let’s rein it in:
- Verify the wiper arm: Make sure the wiper arm is securely attached. A loose arm can lead to erratic behavior.

- Lubricate the wiper mechanism: A squeaky wiper can benefit from some lubrication. Grease up the pivot points to reduce friction.
- Check for obstructions: A stray leaf or debris stuck in the mechanism can lead to noisy wiper action. Clean out any foreign objects for some peace and quiet.
