Okay, sorry, but the answer is yes. the dash has to be removed to gain access to the top of the heater case. I attached a picture for you to view.

Has the actuator been confirmed as the failure?

I have replaced the radiator, thermostat and checked the heater core. I get about thirty seconds of heat then it goes to cool air.

Okay, if you get some and it goes to none I doubt it is the actuator.
move the heat/cool control back and forth and see if you hear the mode door moving.
Are both heater hoses hot to the touch under the hood? It sounds like you have a clogged heater core.
