Sub-steps:
1. Start the vehicle and turn on the HVAC system.
2. Set the system to both recirculate and to draw outside air; observe any differences in window fogging.
3. If the system is not functioning properly, consider checking or replacing the HVAC blower motor or repair the HVAC control module.

5. Inspect for Water Intrusion
