why does my Honda Pilot have a musty smell coming from AC vents

Solution

1. Preparation

• Gather tools and parts:
  • Safety glasses and gloves
  • Screwdriver set
  • Vacuum cleaner (with attachment for tight spaces)
  • Disinfectant spray (suitable for HVAC systems)
  • New cabin air filter (if necessary)

2. Remove Cabin Air Filter

• Open the glove compartment and remove any contents.
• Locate the cabin air filter access panel (usually behind the glove compartment).
• Release the clips or screws holding the panel in place and remove it.
• Take out the cabin air filter and inspect for dirt, mold, or moisture.

3. Clean the Evaporator Core

• If accessible, locate the evaporator core (often requires removal of the dashboard).
• Use a vacuum cleaner to remove dust and debris from the core.
• Apply a disinfectant spray to the evaporator core to kill mold and mildew.

4. Clear the AC Drain

• Locate the AC drain tube, usually found underneath the vehicle.
• Use a flexible wire or compressed air to clear any blockages that may prevent proper drainage.

5. Replace Cabin Air Filter (if needed)

• If the cabin air filter is dirty or moldy, replace it with a new one.
• Reinstall the access panel and secure it with clips or screws.
• Reorganize the glove compartment contents.
