Solution

1. Preparation

Gather tools: screwdriver set, flashlight, vacuum, and moisture absorber.
Ensure the vehicle is parked in a dry and safe area.

2. Inspect and Replace Weather Stripping

Sub-steps:
1. Use the flashlight to inspect the weather stripping around doors and windows for tears or gaps.
2. If damaged, remove the old weather stripping using a screwdriver.
3. Clean the area with a damp cloth to remove any residue.
4. Measure and cut new weather stripping to fit.
5. Apply the new weather stripping, ensuring a snug fit and proper adhesion.

3. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter housing, typically behind the glove box.
2. Remove any screws or clips securing the glove box and lower it to access the filter.
3. Slide out the old cabin air filter and check for dirt and debris.
4. Insert the new cabin air filter according to airflow direction indicated on the filter.
5. Reassemble the glove box.

4. Check and Repair HVAC System

Sub-steps:
1. Turn on the vehicle and set the HVAC system to 'defrost' mode.
2. Verify that the air is blowing through the defrost vents.
3. If not, inspect the HVAC controls for functionality.
4. Check for refrigerant levels if the AC isn’t cooling effectively, using a refrigerant gauge.
5. Repair or recharge the HVAC system as necessary.

5. Address Any Water Leaks

Sub-steps:
1. Remove any carpeting or mats to inspect for moisture.
2. Use a wet/dry vacuum to extract any pooled water.
3. Check for blockages in drainage channels or sunroofs.
4. Seal any leaks found using appropriate sealant.
