Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a well-ventilated area.

2. Inspect and Replace Weather Stripping

Sub-steps:
1. Remove the door panel if needed to access the weather stripping.
2. Inspect the weather stripping for cracks, tears, or signs of wear.
3. Clean the area where the weather stripping adheres using a mild cleaner.
4. Replace damaged weather stripping with OEM or high-quality aftermarket parts.
Tools Required: Screwdriver set, trim removal tool, utility knife.

3. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter compartment (usually behind the glove box).
2. Remove the glove box as necessary.
3. Take out the old cabin air filter and inspect for dirt and blockages.
4. Insert the new cabin air filter in the correct orientation.
Tools Required: Screwdriver set.

4. Address Water Leaks

Sub-steps:
1. Inspect door seals and window seals for any wear or misalignment.
2. Replace any worn or damaged seals with new ones.
3. Test for leaks by spraying water over the closed doors and observing for water ingress.
Tools Required: Water spray bottle.

5. HVAC System Check

Sub-steps:
1. Start the vehicle and set the HVAC system to defrost mode.
2. Check for proper airflow from the defrost vents.
3. If airflow is inadequate, inspect the blower motor and associated components for functionality.
Tools Required: OBD-II scanner (if additional diagnostics are needed).
