I would check the thermostat, the blender door, heater core and the coolant level one of these things could be causing no heat.

I have done all these things, installed new thermostat.

check for a heat control valve that opens up the flow on the heater hose to the heater core.this is located on the in side to the heater core feel both hoses to see if 1 side is hotter then the other with heat on high
