No heat

The blend door actuator is behind the center of the dash.

No it's a electric actuator and the glove box part is if your replacing the blend door with the dorman repair kit.

Should be able to see it to the left side of the glove box up under the dash

Your welcome make sure you check the shaft of the blend door to see if uts broken

First, check the heater hoses at the core. They both need to be hot. If one is hot and one cold, the heater core is clogged.

If they are both hot, then the blend door motor has failed.

You can flush the heater core by using a garden hose and flow both ways.

The blend door motor is much tougher.

Yes it is more than likely a mixing door. And they will have to take the dash apart. But I would definitely get several opinions. The dealer is very very expensive and you could save several hundred dollars, going elsewhere. So check it out.

Feel the heater hoses at the bulkhead when the engine is hot. Both hoses should be hot. With the engine running, move the temperature control lever/**** completely both directions. You should hear the blend doors in the airbox moving. If not, check the connections, wiring, and vacuum lines. Make sure the vacuum lines are drawing a vacuum. If so equipped, make sure the heater control valve just inside the engine compartment is operating properly when the temperature control is moved. Make sure the cooling system is full and the thermostat is operating properly (look in the radiator with the engine one and at temperature-this will also tell you if the water pump is working properly).

The first thing I would do is make sure both your heater hoses going into the heater core are getting really hot when the engine is up to normal operating temp.

No, and I believe I just addressed your heat issue.
