New thermostat, all hoses are hot, flushed heater core. No air bubbles, left the car on with no radiator cap for almost an hour. Door blend works, valves operates fine to but still no heat! Help!!!

 

could be a bad radiator clogg not enough flow

 

Wow...I'm a little stumped, personal opinion. T-stat installed incorrectly or heater core just bad...but don't they leak when they are bad?? Or heater hose leaking?

 

Does the blower motor come on at all?

 

could be blower motor not working.

 

check the cable latch on the valve on the hose by the fire wall inside the engine, sometimes the vent on the climat control seems to move fine from cold to hot but the cable can get stuck leaving the valve closed, manually opent the valve if thats the case.

or your blower is not working but if its blowing cold air its working.
