Where is the blend door in a 1991 Lincoln Town Car?

In a 1991 Lincoln Town Car, the blend door is located within the HVAC (heating, ventilation, and air conditioning) housing, typically behind the dashboard. To access it, you may need to remove the dashboard or specific panels to reach the HVAC assembly. The blend door controls the mix of hot and cold air by directing airflow, allowing for temperature regulation inside the cabin. If you're experiencing issues with temperature control, it may be necessary to inspect or replace the blend door actuator or the door itself.
