my Honda CR-V Sixth Generation (2023-present) has a weird smell inside, what could it be

Solution

1. Preparation

• Gather tools and materials.
• Ensure the vehicle is parked on a flat surface with the engine off.
• Wear gloves and a mask if dealing with mold or chemicals.

2. Replace Cabin Air Filter

• Remove the glove compartment by unclipping the retaining tabs.
• Locate the cabin air filter housing and remove the cover.
• Pull out the old cabin air filter and inspect it.
  • Tools Required: Flathead screwdriver (if needed for clips)
• Insert a new cabin air filter (ensure it's oriented correctly).
• Reassemble the glove compartment.

3. Clean HVAC System

• Use an HVAC cleaning spray to eliminate mold and odors:
  • Insert the spray nozzle into the air intake (usually located near the windshield).
  • Activate the HVAC system on recirculate mode, allowing the cleaner to circulate through the vents.
• Allow the system to dry with the windows open.

4. Address Dampness

• Remove any wet carpets or mats; dry them thoroughly or replace if necessary.
• Check for leaks in door seals and windows; replace weather stripping if damaged.

5. Inspect and Repair Any Fluid Leaks

• Check under the vehicle for signs of oil, coolant, or other fluid leaks.
• Tighten any loose fittings or seals, or replace damaged components as necessary.
  • Tools Required: Socket set, wrenches
