Heater blowing cold air !!!

First, make sure you were moving the correct actuator - there is the blend door actuator (the one you needed for this experiment) and the diverter (which directs air to defrost, floor, vents, etc.)

If you moved the blend door with no hot air coming out no matter what, that suggests that the problem is the heater core is plugged or not getting warm water from the engine for some reason. In that case, make sure the hoses are not crimped or collapsed. Most likely that is a plugged heater core.

I'll take a pic tomorrow and post it up , you can actually see it once you drop the glove box to your left it goes up and down so
