It can't be the thermostat or the blower - in the case to the thermostat the engive will overheat pretty fast and in case of the blower you would get heat when driving.
Your problem is with the control valve on the heater and its commands: either the valve is blocked in the shut position (or it's clogged) or is no longer commanded. The temperature button uses some cables to pass the command to the lever of the valve - you must remove the central console cover and check the cables; if the cables appear ok and move accordingly to the position of the button then check the lever; if the lever moves then you must replace the valve - it's either defective (the lever no longer rotates the flap in the valve or the valve is clogged.

Check the fuse located underneath the drivers side steering wheel. Remove the fuse box cover lid and look for the defroster and heater blower fuse. Replace the two fuses with the same exact number fuse (each fuse is color coded and has a number on the top of it) After you replace them you will get heat in your passenger compartment and the defroster will work

05 sorento heater not heating everything else works fine but no heat?

First, check your coolant if it's full, or has gone deplete because there been issue with the sorentos which kia doesn't acknowledge of a loose or leaking radiator plug which loose coolant. With low coolant, the heating system would not work since it's only sucking in air. 2) If that is not the case, then you maybe looking at a case of a plugged heater core, or thermostat being stuck open. The position of the air temperature valve in the air conditioning housing under the dash (which determines how much of the total airflow is permitted to pass through the heater) is stuck. The valve position determines the warmth of the overall air flow that is sent into the passenger compartment. This door-like valve redirects air flow. In some positions such as defrost the AC comes on to dehumidfy the air to aid in clearing the windows during high humidity. You may need to take a look behind the glove box compartment and dissemble the blower motor and clean around. It may work, if not you will need to get it to a shop as the heater core probraly bad or leaking.

2002 Kia Spectra heating problem

Have you checked the heater tap to see that it is working?If the heater tap is working you can undo the hoses at the firewall and use a garden hose to check that the water is flowing freely through both the heater radiator core and the engine.poke the garden hose up one of the hoses you removed and turn the water on make sure water is flowing freely out the other hose,if clear repeat test on heater radiator core.If heater core is blocked and you have compressed air you can gently flush the core by blowing the water through it.
