No heater operation - blend door actuator location?

Mike R1025 · 2017-11-01T13:05:03+00:00

With the blower on and the thermostat set to cold and the vent blowing on your face it will blow cold air on you. As soon as I switch the thermostat to full hot, the air comes out of the defrost. It is a little warm but not enough to heat the vehicle. So basically no heat. What I have done so far: Replaced coolant and burped the system, replaced the thermostat, replaced the blend door but with same actuators, replaced control panel, flushed the heater core and heater core lines.

Are both heater hoses sort of equally uncomfortably hot to hang on to when the vehicle is at operating temperature? (hoses to the heater core)

I was checking to see if there was circulation through the core.

Could be stopped up again if the hoses were cooler than normal.
