Solution

1. Preparation

Gather tools and materials: gloves, safety goggles, flashlight, replacement cabin air filter (if needed), and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Cabin Air Filter

Step 1: Locate the cabin air filter access panel, usually found behind the glove compartment.
Step 2: Remove the glove compartment by detaching any clips or screws.
Step 3: Open the access panel and remove the old cabin air filter. Inspect it for dirt, debris, or a strong odor.
Step 4: Install a new cabin air filter, ensuring it is oriented correctly.

3. Check for Fluid Leaks

Step 1: Inspect the engine bay for any signs of fluid leaks, particularly from the coolant reservoir, brake fluid reservoir, and power steering fluid.
Step 2: Clean any spilled fluids with a suitable degreaser to eliminate odors.
Step 3: If leaks are found, replace the faulty seals or hoses as necessary.

4. Clean HVAC System

Step 1: Use a disinfectant spray specifically designed for HVAC systems to eliminate mold and mildew.
Step 2: Spray the disinfectant into the fresh air intake vents while running the fan on high.
Step 3: Allow the HVAC system to run for a few minutes to ensure the disinfectant circulates through the system.
