Solution

1. Preparation

Gather tools and materials needed for the inspection and repair.
Safety gear: gloves and safety glasses.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter access panel, typically found behind the glove compartment.
Open the glove compartment and remove any contents.
Disconnect the stop arm on the glove compartment to allow it to drop down.
Remove the access panel to the cabin air filter.
Take out the old cabin air filter and inspect for dirt or moisture.
If necessary, replace it with a new, dry filter (use OEM recommended filter).
Reassemble the access panel and glove compartment.

3. Check and Repair Seals

Inspect door seals, window seals, and sunroof seals for any signs of wear or damage.
Replace any damaged or worn seals with new OEM parts.
Use silicone sealant on any gaps or areas where water might enter.
Ensure that all windows and doors close properly to create a tight seal.

4. Clean and Clear HVAC Drain

Locate the HVAC drain tube, usually under the vehicle near the firewall.
Use compressed air or a flexible brush to clear any blockage in the drain tube.
Verify that water drains properly outside the vehicle when the AC is running.

5. Inspect Windshield Sealing

Check the windshield for any visible gaps or bubbling that may indicate improper sealing.
If necessary, reseal the windshield using a high-quality automotive sealant to prevent leaks.
