Toyota Rav4 Water Leak Passenger Side

Common Causes of Water Leaks

  • Clogged Sunroof Drains: If the sunroof drains are blocked, water may overflow and leak into the cabin.
  • Damaged Door Seals: Worn or torn door seals can allow water to seep inside during rain or car washes.
  • HVAC Drain Blockage: A clogged air conditioning drain tube can cause condensation to back up and leak onto the floor.
  • Windshield Seal Issues: Improperly sealed windshields may let water enter the vehicle.
  • Body Panel Gaps: Misaligned or damaged body panels can create gaps where water might enter.

How to Identify the Source

  • Inspect Door Seals: Check for cracks, gaps, or wear in the rubber seals around the doors.
  • Test Sunroof Drains: Pour a small amount of water into the sunroof drain holes and see if it drains properly under the car.
  • Check HVAC System: Run the air conditioning and observe if water drips underneath the vehicle. If not, the drain tube might be clogged.
  • Examine Windshield Edges: Look for gaps or loose seals around the windshield.
  • Look for Damp Areas: Trace wet spots to find where water is entering.

Fixes for Water Leaks

  • Clear Sunroof Drains: Use compressed air or a flexible wire to unclog blocked drains.
  • Replace Door Seals: Install new rubber seals if they are damaged or worn out.
  • Unclog HVAC Drain Tube: Use a thin tool or compressed air to clear any obstruction in the drain tube.
  • Reseal Windshield: Apply automotive-grade sealant around the windshield edges or consult a professional for proper resealing.
  • Repair Body Panels: Realign or repair gaps in body panels with professional help if needed.

Preventing Future Leaks

  • Regularly clean sunroof drains to prevent blockages.
  • Inspect door seals periodically for wear and tear.
  • Ensure proper maintenance of the HVAC system, including clearing drain tubes.
