Do you have to take the whole dash off to replace the HVAC actuator?

Good afternoon.

Which actuator? There are three different ones. Which function is not working?

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.

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.
