the hot water from the engine does not enter the heater coil placed under the dust board of the car because the water valve controlling it is not being activated. Possible cause no supply of 12 volts or the coil of the valve is already burnt out. Have it check by a professional car aircon technician. But first look up for the fuse of said control possibly you've got only a blown fuse. Try to check the fuse using visual inspection and multitester.
fuses are ok

How hard is it and how do you fix a 1986 Ford Thunderbird heater core that is blowing steam even when the heat is off?
Replace the heater core. It is leaking.
Why is your heater blowing constant hot air even when set to cold?
Heater control valve stuck open. Possible blend air door failure.
Why doesn't your 1989 ford ranger xlt heater get hot even though you just put in a new thermostat and it is full of antifreeze?
Check both the supply and return heater hoses from engine to heater for blockage or clogging: remove them and flush. Also check the inlet and outlet pipes on the engine and heater core for gunk buildup and leakage.
Why does your hot water tank keep blowing the pilot out when it shuts off?
If it is windy outside, you may be getting just enough of a breeze to blow out the pilot light -even though the covers are shut. My heater is in the garage, and even w/ the garage door shut and the covers on the heater shut, very windy weather can still cause enough of a draft to blow out the pilot. You could try to find something to block drafts around the heater such as a hot water heater blanket.
On a 96 S-10 Blazer why would there be only cold air coming from the vents even though the engine temp is norm at 240 deg?
Your heater core may be clogged. Have the heater core flushed and refill the system with fresh coolant.

How do you fix a heater that wont blow air in a 94 Nissan Sentra?
first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all. The first thing i would check is if the fan motor is blowing any air at all. If not u need to put in a new heater fan motor. first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all.

Your heater core is leaking in it's housing box and blowing moist air through the heater/defroster. Try bardall radiator stop leak. If no help, install new heater core. Chuck.
How do you fix the heat in a 94 Chevy S-10?
add water to the radiator. believe that. if there is no water flowing through the engine, your heater will only blow cold air. if there is no water flowing through the engine and your heater is only blowing cold air, and not HEATING, your heater core is probably going out or will be soon. most people believe that if you have no water in the engine then your temperature gauge will run hot and you will know that you are overheating the engine. WRONG! your temp gauge only measures WATER temp. But if there is no water to measure, there is no temperature rise showing on the dashboard gauge. if you have NO WATER in the engine you can seriously overheat your engine and not know it because the gauge is not getting any hotter than usual (sometimes your gauge will even read cooler than usual).
Why is your fan heater control switch is permanently on full even though the switch is on off?
It could be the high speed heater motor relay is stuck on or the switch itself is broken.
How does a heater control valve work in a car?
A heater control valve is simply a water valve which allows more or less water to circulate through the heater core, depending on how much the valve is opened. When the engine warms up it heats coolant (mostly water) in the water jacket of the engine. To keep the engine from overheating, the water pump circulates water through the radiator once the engine temperature reaches the set-point of the thermostat. When it's cold outside the engine STILL reaches a temperature that allows you to make use of the engine heat when you open the water valve of the heater. Heater control valves take many forms but basically they all do the same thing; they open to allow heated engine coolant to circulate through the heater core or they close to stop the coolant from flowing. Heater control valves can be manual (cable controlled or even lever controlled), vacuum (which allows the engine vacuum to control the position of the heater control valve based on where you set the control knob) or electrical which allows for greater flexibility and even allows the auto manufacturer to connect the heater controls to a computer or other electronic control device.
