“Why do streaks appear only on certain parts of the Haval Jolion’s windshield during o r after rain?”

During rainy weather in Pakistan, you observe that certain areas of your Jolion’s windshield have streaks o r water marks that don’t clear properly with wipers. What factors—such as windshield glass coating degradation, dirt accumulation, o r wiper arm misalignment—can cause this selective streaking? How should you inspect and address the problem to restore uniform clear visibility?

Dirty windshield glass: Dust, pollen, oily residue, and road grime build up on the glass, causing the wipers to smear dirt instead of cleaning.

Worn o r damaged wiper blades: Old blades become hard, cracked, o r develop uneven edges that don’t contact the glass properly.

Low-quality o r wrong washer fluid: Some cheaper o r improper fluids don’t clean well and leave residues. Hard water in tap water can leave mineral deposits.

Contaminated washer nozzles: Blocked o r misaligned nozzles spray unevenly, leading to inadequate cleaning.

What to do:

Clean the windshield thoroughly with a good glass cleaner and microfiber cloth, removing any oily film o r deposits.

Inspect and replace worn wiper blades with quality OEM o r reputable brand replacements.

Use proper windshield washer fluid formulated for Pakistani conditions with detergents and anti-mineral agents. Avoid plain water.

Check washer nozzles for blockages and adjust spray pattern if needed.

Occasionally clean wiper blades with a damp cloth to remove built-up dirt.
