Here is a picture of the inspection cover, take this off and you can see if your blend door is working.

Just an FYI: On vehicles equipped with Automatic Temperature Control, the cover is held on with 3 screws. On vehicles with manual HVAC, the evaporator housing must be cut and the heater blower resistor removed to see the blend door.
