Common Causes Behind The Wet Floor Dilemma

Clogged or Blocked Drainage System

  • In the Altima, this typically involves the drainage channels around the windshield or sunroof. 
  • When these channels get onboard with debris like leaves, dirt, or twigs, water can’t correctly drain away, leading to leaks inside the cabin during rainfall.

Damaged or Worn Weather Stripping

  • The weather stripping around the driver’s side door and windows can deteriorate over time due to exposure to the elements and regular wear. 
  • If the weather stripping is out of shape or improperly in position, rainwater can enter the vehicle and pool on the floor.

Leaky Door Seal

  • Besides the weather stripping, the door seals may develop leaks or gaps. 
  • Over time, these seals can degrade, allowing water to seep into the interior during heavy rain or car washes.

Faulty Window Seals

  • Suppose the window seals are out of shape or not in good condition.
  • In that case, water can infiltrate around the edges and accumulate on the driver’s side floor.

Leaking Heater Core

  • A leak in the heater core can result in coolant fluid seeping into the car’s interior. 
  • Notice a sweet or intense smell inside the cabin or suspect your engine coolant levels are dropping without any visible external leaks. 

Malfunctioning Air Conditioning Drain

  • The air conditioning system generates condensation, which should drain away. 
  • If the drain malfunctions, the water can leak into the car, usually on the front passenger’s side. Still, it may also find its way to the driver’s side.

How to Fix a Clogged AC Drain Line

Worn or Damaged Floor Pans

  • In older vehicles or those that have endured harsh conditions, rust or damage to the floor pans can allow water from the road or external sources to enter the cabin area.

Accident Damage or Poor Repairs

  • If your vehicle has been in an accident, especially around the front or sides, there could be unseen structural damage that might be causing water leaks.

Step-By-Step Solutions To Help You Tackle The Issue

  • Look for damaged weather stripping, seals, or blocked drainage channels around the windshield, sunroof, doors, and windows. Clear any debris or obstructions in the drainage channels.
  • Check if the floor mats are damp, and ensure they are properly secured, not allowing water to seep underneath. If they are wet, remove them and let them dry completely before putting them back in place.
  • Ensure the air conditioning system’s drainage tube is not clogged or obstructed, as this can cause water to back up and enter the cabin. If you find any blockages, clear them carefully using a small brush or compressed air.
  • Inspect the floor pans for rust, holes, or any signs of damage. If you find any issues, you may need to consult a professional auto body repair shop to address the problem correctly.
  • While you are troubleshooting and waiting for repairs, keeping the interior as dry as possible is essential. Use absorbent materials like towels or a dehumidifier to remove moisture from the floor and carpets.
