Solution

1. Preparation

Tools Required:
- Screwdriver set
- Flashlight
- Wet/dry vacuum (if necessary)
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery if working on electrical components.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter access panel, usually found behind the glove compartment.
Open the glove compartment and remove any contents.
Unclip the panel to access the cabin air filter.
Remove the old filter and inspect for dirt or blockages.
Install a new cabin air filter as per manufacturer specifications.

3. Clear Drainage Tubes

Identify the drainage tubes for the sunroof or windshield.
Use a flexible wire or compressed air to clear any blockages in the tubes.
Test the drainage by pouring a small amount of water into the sunroof or windshield channel and ensuring it drains properly.

4. Check for A/C System Issues

Inspect the A/C system for leaks using a UV leak detection kit.
If refrigerant levels are low, recharge the system with the appropriate type of refrigerant (R-1234yf for newer models).
Ensure the A/C compressor engages and the system blows cold air.

5. Inspect Weather Stripping and Seals

Visually inspect the weather stripping around doors and windows for wear, cracks, or misalignment.
Replace any damaged weather stripping to ensure a proper seal.

6. Test Heater Core

Inspect the heater core for signs of coolant leaks, such as a damp passenger side floor.
If a leak is found, replace the heater core according to the manufacturer's specifications.
