Solution

1. Preparation

Gather tools: flashlight, gloves, and an OBD-II scanner.
Ensure the vehicle is parked in a well-ventilated area with the engine off.
Disconnect the vehicle’s battery to avoid electrical issues while inspecting.

2. Inspect Cabin Air Filter

Locate the cabin air filter access panel usually found behind the glove compartment.
Open the glove compartment and remove any contents.
Release the compartment's stops to allow it to drop down.
Remove the cabin air filter and inspect it for dirt, mold, or blockages.
If dirty, replace the filter with a new one (OEM recommended).

3. Check for Fluid Leaks

Inspect under the dashboard for any signs of fluid pooling or dampness.
If there is evidence of a leak, identify the source (e.g., coolant, brake fluid).
Clean any spilled fluids using appropriate absorbent materials.

4. Examine Climate Control System

Start the vehicle and turn on the climate control system.
Listen for any unusual noises (e.g., grinding, clicking) that may indicate a failing blower motor or debris in the fan.
Ensure the air flow is consistent and check for any strange smells during operation.

5. Inspect Wiring and Connectors

Visually inspect the wiring and connectors under the dashboard.
Look for any signs of burnt or melted wires which could indicate overheating.
Repair or replace damaged wires as necessary, ensuring proper insulation and connection.

6. Clean and Sanitize Interior

If a musty smell persists, clean the interior surfaces with a disinfectant suitable for automotive use.
Consider using an ozone generator or air purifier to eliminate lingering odors from the cabin.
