In a 1998 Mercury Mountaineer, the blend door is located within the HVAC system, typically behind the dashboard. To access it, you often need to remove the dashboard and some interior panels to reach the climate control assembly. The blend door regulates the mixture of hot and cold air, allowing for temperature adjustments in the cabin. If you're experiencing issues with heating or cooling, it may be worth checking the blend door actuator as well.
