Question
I replaced thermastat flushed system new heater hoses new heater core new blend door still have no heat
Most Heater systems employ Vacuum Servos to direct the Air Flow from the outside, to either the Chamber where the Heater Core sits, or the A/C side of the vent system. It is possible that either one of the Servos has ceased to function, due a bad diaphragm, or the line to it has a crack in it. Without a "Factory Service Manual" though, it will be difficult to determine which Servo may be the culprit.
If your car uses a "Heater Valve", as is the case on many older vehicles, mostly 1970's on back, the Valve may be stuck shut.
