Check thermostat and water pump.the water pump could be working good enough to ke the engine cool but dosnt have the pressure to push it thru. i ran in to this prob be for no heat and the engine didnt over heat. the antifreeze ate the blades off the water pump. it was crazy.

SOURCE: not getting heat in cab

Is the blower running at all? Also, make sure the main air intake vent is free of obstructions.

Also, a vacuum leak could cause the actuator to not function correctly. I'd check into the vacuum lines if all else fails. I've had too many cars here with heat/air problems due to vacuum loss and the actuators not switching correctly.

be sure you have no coolant leak and check if you have a blead valve on the engine for the coolant if you do, blead the air out

Is the blower motor working? If not that is what it is. If it is working then check heater coil out, Could be bad heater coil.

SOURCE: Have no heat. Have replaced heater core,

I don't know your vehicle, but does it have a blower door tucked in where the heater core is? If it DOES and that's broken then it could be the whole problem. It would mean it isn't switching from the A/C side of things to the heat side of them. Hope this helps, good luck! Also, just looked up the proper name for what I'm talking about, it's called a "blend door" and I think your car has one. It's what I would check, again, good luck!

Where is the heater fuse located for my 2001 Mitsubishi eclipse

Have them flush your heater core. Often all of the gunk that runs through the engine settles in the engine core. Even after you flush the system, it regularly remains and re-pollutes, as you have experienced. It will continue until you either flush or replace your heater core.

Heater not working blows cold air. Replaced thermostat, flushed radiator fluid and there's no water on floor in the car. Could it be a fuse?

it could be an cloged up heater core, or it could be like mine was. had to replace the water pump, when i pulled it off almost all the fins was gone, there for not circulating right.

2001 eclipse no heat flushed heater core with air and water also replaced radiator and thermostat

Stick your head under the driver side dash and look on the side of the blower motor check to see if the wire to the damper is moving through the small plastic conduit. over time the wires lose their rigidity and instead of moving the damper it will bend. Let me know if these look normal

Have the water pump checked for operation, also have the radiator checked to see if it may be plugging up. Flushing the radiator may help also.

Heater wont get hot

Make sure the temp door is moving when you change the temp.then change the thermostat out with a new one.Bleed the system of all the air in the cooling system.If still,no heat,remove the heater hoses from the heater core,and flush the heater core out with a water hose.In one pipe,it will flush out the other pipe of the heater core.
