heater wont get hot on 2002 Jeep Liberty

Air blows cold out the defrost and barely warm out the vents. I changed the blend door actuator, check heater core it was good. Thermostat works fine, system has been flushed and I have a new radiator.

Is the blend air door operating properly? What if you disconnect the actuator and more the door manually?

IS there a diagram of how to fix the blend door actuator? I know the radiator and water pump are good because they are new? I have check the fuses and up blow fuse! The cold/hot switch does not work but I was told that the blower motor resister could be the problem? Is there any way you can reply with a fix or help with this problem?
