Solution

1. Preparation

Gather tools: flashlight, screwdriver set, vacuum, and a moisture meter.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter housing, typically behind the glove compartment.
2. Remove the glove compartment to access the filter.
3. Remove the old cabin air filter and inspect for dirt or blockage.
4. Install a new cabin air filter (ensure it is the correct type for the vehicle).

3. Check Door and Window Seals

Sub-steps:
1. Visually inspect door seals for cracks, tears, or improper seating.
2. Check window seals and sunroof for similar issues.
3. Replace any damaged seals with OEM parts to ensure proper fit.

4. Clear HVAC Drain Tube

Sub-steps:
1. Locate the HVAC drain tube, usually found under the vehicle near the passenger side.
2. Use a compressed air tool or a flexible wire to clear any obstructions.
3. Ensure water drains freely when the air conditioning is running.

5. Test HVAC System Functionality

Sub-steps:
1. Start the engine and turn on the HVAC system to the A/C mode.
2. Monitor the air temperature from the vents — it should be cool if functioning correctly.
3. Observe if condensation forms on the evaporator coil (a typical part of A/C operation).

6. Inspect for Water Intrusion

Sub-steps:
1. Check for drainage issues from the sunroof by pouring a small amount of water and ensuring it drains properly.
2. Inspect the windshield area for any gaps or damaged sealant.
3. Repair or reseal as necessary using appropriate sealant.
