no matter where heater mode control is set, only the vent air works. on 1996 Dodge Stratus

I checked ALL fuses. Also checed hot leads to switch. One is constent hot, other is hot with key turned to run position. How do I test heater control mode switch? Should I be looking further to the distribution box?

maybe the mode door is not working
is there a way to check the mode selector switch for defectiveness? Is the mode door electric or vacume activated
