HEATER NOT WORKING

Heater Blows Cold Air When Idling But Heats Up When Accelerating.

My A/c Works, Fans Work On All Speed Settings, Car Does Not Overheat, Blower Motor Works. But I Have No Heat. Just Blows Cold Air.

Just Blowing Cold Air. I Already Drained And Replaced Coolant, Flushed Lines, Blender Actuator And Temp Control Valve. Gauges Are Working...

Everything Works But The Slider To Take To Heater Is Not Working.

The Inside Electrical Was Not Working Much And Some Other Things Were Running Poorly As Well. We Had The A/c Repaired And The Radiator...

Loss Of Hot Air Out Of The Front Defroster And Dash Vents, It Blows Cold Air Out Of The Floor And Back Heater.

I Only Have One Heat Control Knob. When The Heat Is On It Blows Hot On The Passenger Side And Cold On The Driver's Side.

I Replaced Blend Door Actuator And Climate Control No Heat. I Did Not See Blend Door Actuator Move. Do I Have A Fuse Out And If So Can...

When The Heat Is On, The Driver's Side Is Only Cold Air, But Passenger Side Is Warm Air.

The Fan For Heater Always Works But The Heat That Comes Out Is Only There Once In A While. Was Working All The Time?
