I recently had a problem where the car was not blowing air into the cabin. I Changed the final stage resistor (also known as the "hedgehog")and all is good. its located in the driver footwell, remove the panels under the steering wheel, and you will see it stuffed up in the top left corner.

Al, Heaters blend door actuators are malfunctioning or if your car is equipped the call it a heat shut valve.

Go to the front power distribution box and check 30A fuse 20 (GRN/BRN wire) which feed power to the blower relay. When the ignition switch is in START or RUN position, the relay closes and power is fed to the final stage unit. Depending upon the state of the automatic climate control module, power output from the final stage module is applied to the blower motor. If checking all this does not solve the problem, you may have a clogged heater core
sounds like the temperature blend door is either jammed or the actuator is shorted ou. when the temperasture control is moved you should hear the door moving...my guess is you are not hearing that..the actuator would be attached to the heater plenum behind dash/glovebox area...becareful to test the correct one as there will be a fresh air actuator and a mode door actuator as well...you can determine which one is which by changing the positions on heater head from hot/col, floor/defrost, recirculate and fresh air settings..each setting will move its designated actuatror..the one not moving would be you temp actuator....have fun!
both hoses is hot signifies thatcoolant circulation is just fine check the blend door actuator it might be stuck.pan the heater temp controller from hot to cold do you feel any change in temp of the air from the blower?if you dont feel any change check the blend door actuator
The E46 blower resistor is harder to remove than the E39 . Open the Glove box. Remove the three phillips screws across the top of the open box. Remove the two phillip screws that are deeper in on the sides of the open box(nine and three o'clock). Hard to see, use your flashlight. With these five screw removed remove the glove box.Disconnect the flashlight charger plug, and the glove box light connector. Pay attention to the wire routing. Remove plastic cover behind glove box.Locate motor and metal link to one of the a/c doors. Remove the metal arm from the plastic clip. Slide motor out and disconnect.There is an odd shaped black plastic piece with two T-20 or 25 Torx screws that need to be removed.Remove plastic piece.The Final stage is located behind the metal arm for the a/c door.Remove the floor heater duct for more room. You may or may not feel the need. If you wish pull on the leather extension to the center console outward until you hear a loud plastic cracking. Stop. Take a deep breath and know that you have broken nothing important Remove heater duct careful not to break the blend air door cam (white) and the lever connected to it (black). You can pull that black lever out if you are patient. Back to the final stage now that you have more room. It is the component with the 5 0r 6 large gauge wires on the connector. Push back the black plastic clamp while pulling/wiggling on the connector. The final stage should come out, then disconnect the connector. Reinstall all. Make sure the heater duct is installed properly if you removed it.
It sounds like your cabin air filter has stopped up common problem on these cars. You have to remove the glovebox to get to it. If this filter stops up, your fan will be running on high but hardly anything will come out of the vents.
Usually when your system stops blowing hot air it is your thermostat that is shot. That would be located where your top hose of your radiator meets the top of the engine. Check that because its easier to replace than a tear down to get to the actuator. Hope that helped.
