When turning on my heater I discovered only the defrost is working. No air is coming out on any other settings and when turning the setting all the way right(defrost mode) It seems to be on the setting but the knob doesn't look as if its all the was over. If anyone has had this problem or knows how to fix it I'd appreciate your help. My email is [email protected]

check the controls for the vent doors.

I assume your heater setting is electric control, if so either your defrost and floor heat switch failed or wire problem. For the air not hot, check the heat control valve on the top of the hose it should be in front of the firewall. I don't know your car is using mechanic valve or electric control valve. Anyway check there first. Good luck.

you might want to check the module under the glovebox

Make sure the vent system is set to draw air from outside. If it is set to recirculate the same air that's inside the vehicle without drawing fresh air from outside, the resulting humidity that builds up inside the vehicle can fog the windows even when you run the defrost. You can also try opening the windows a bit to get some more air moving inside.
If it still fogs when the vents are set properly, you may have a leaky heater core. The heater core is a small radiator that is located under the dash that the heater system blows air through to heat the inside of your car and provide heat to defrost the windshield. The fog may be coming from the heater core leaking hot coolant steam that's being circulated through the defrost system. If this is so, you will need to replace the heater core.

I bet it is your blender actuator.

Check to see if the duct hose to the defroster vents has come loose. If air is blowing out under the dash when you have the control set to defrost, then this is likely.

Sounds like the flap valve in your vent system that allows air to go to the defrosters is either jammed or broken. Unfortunately you will have to take the vent system apart to look.

Most cars and trucks are set for the A/C to run in defrost. Even if you have the temp at hot. The air will pass through the evaporator core first witch draws moisture out of the air. That is why you see water dripping out of a car with the air on and sitting at one place.

The dry air makes the defroster work faster. It is a safety feature.

replace the vacuum mode control switch in the heater control, this is a dealer only part.

The heater only blows HOT air when set on defrost or floor settings. If you have the lever set for vent, only cold air will come out. Check to make sure you set the controls to floor or defrost. This is standard for all Festiva's.
