I have a 2002 Ford torus that doesn't put out enough heat in the winter I have flushed out the heater core and change the thermostate but it still don't get warm enough and it doesn't have a...


If both heater hoses are getting hot then you know the coolant has to be flowing and the core should be hot.
What you will have to do is locate the blend air door servo.
The blend air door is a door (or flap) between the heater core and the A/C evaporator (even without a/c there is still a door to control the cabin temp)
Early vehicles with the slider controls used a cable but the later vehicles with a rotary knob or digital buttons use a servo to rotate the door mechanism.
The servos can go bad and the switches as well.
But from the sounds of it, your door is not moving to allow the heat through the vents.

We just bought a 1999 GMC Jimmy and the heater doesn't work. The fan blows but there is no heat. The air conditioner works fine.


Could be that the heater core is disconnected, there are two hoses that attach to the heather core that come out of the engine, this provides hot water to the core thus making the heater work, when the heater core starts leaking water the quick and fast fix would be to bypass the heater core and connect the two hoses together, check under the hood on the left passenger side there should be two hoses about 1" thick see if there are connected together or of they seem to be connected to 2 outlets that come out of the inside of the vehicle. people do that specially if selling vehicle.

Engine heats to proper temp, heater fan works, already replaced termostat. heater core doesn't seem to be leaking.


Find where both hoses are going to the heater core from the firewall side after engine is up to temp.Touch them with your hand.If they are both quite warm the water is flowing thru the heater core. If only one is hot the core is stopped up. If both are hot and still no heat the heater door in the heater box is staying closed.

My heater fan turns on before the car has warmed up. It blows cold air? Any ideas why?


After warmup it still blows cold, or only when cold? Normally the fan will operate independently of engine temp except in some climate controlled vehicles. As long as it blows warm air after engine is at temp that's a good thing. the heater uses hot water from the engine. Obviously the heater can't be warm before the engine is. If it's cold after the engine is hot, there are vacuum controlled "motors" on top of the heater box under the dash that move doors that control heat. Either one of the control motors or one of the doors have stuck or failed. Many also have a control valve on one of the heater hoses under the hood as well. If the engine comes up to temp then the thermostat is good (should be at about 210f) Only remaining item is the core itself which may be internally or externally obstructed.
All this being said, if it's good when the engine is up to temp, leave it alone...it's fine.
