Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle in a dry area and ensure the engine is turned off.
Disconnect the battery to prevent any electrical issues during the repair process.

2. Inspect and Replace Weather Stripping

Use a trim removal tool to carefully detach the old weather stripping from the door frames and windows.
Clean the surfaces where the new weather stripping will be applied to ensure a proper seal.
Measure and cut the new weather stripping to the correct lengths.
Attach the new weather stripping firmly, ensuring there are no gaps.

3. Repair Leaks

Inspect the windshield for cracks or poor adhesion; if found, reapply sealant or replace the windshield as necessary.
For sunroofs, locate the drainage ports and carefully clear any debris with a soft brush or compressed air.
If leaks are found around windows or doors, apply a suitable automotive sealant to create a waterproof barrier.

4. Change Cabin Air Filter

Locate the cabin air filter access panel, typically found behind the glove compartment.
Remove the screws or clips holding the panel in place and take out the old filter.
Insert the new cabin air filter, ensuring it is oriented in the correct direction.
Reattach the access panel securely.

5. Test Air Conditioning System

Start the vehicle and turn on the air conditioning to the highest setting.
Monitor the system for proper operation; listen for unusual noises or check for weak airflow.
If issues are detected, further diagnose the A/C components such as the compressor or evaporator.
