Four possible issues. Start by checking fuses. If you are lucky, someone put the wrong amp fuse in and replacing it will fix things. Bad switch. More likely, bad fan motor or bad blower resistor. You can check the resistor by unplugging the wire connector and remove the part (two screws hold it into the plastic heater cover under the hood on passenger side of firewall) and inspect it for a broken wire. This will look like a small spring or two, and if one is broken, replace part. You can test the fan motor by unplugging the single wire going to the motor, use a jumper wire to BRIEFLY connect straight to the battery and see if it runs or just makes a big spark. Big spark = replace the motor.

SOURCE: heater is blowing but its cold air not hot air 2000 expedition

Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.

2000 ford mustang v-6 heater does not blow warm air at all


If the engine is reaching proper operating temperature and blower is working you could have a bad pressure cap or a low coolant level and if not this then possibly an air lock or a plugged heater core or a defective controller unit.

Heater blows cold air


With the car warmed up,feel the heater hoses,are they both warm/hot near the firewall in the engine compartment?If they are both warm/hot,then the heater core should have circulation through it and it may be a "blend door" issue in the heater a/c assembly.If they are not warm/hot then the heater core could be dirty and plugged up and needs to be flushed.
If the above does not help,a drain and vacuum of the cooling system and vacuum refill will remove any trapped air.
Sometimes,clamping off the top rad hose and holding the engine rpm at 2000 rpm will force trapped air out of the heater core.(Watch temp gauge when trying this)
Lastly,a NEW thermostat doesn't mean its working correctly.
