Did you ever have a coolant leak?
The heater coil and a heater core is the same thing. Hot water circulates from the engine and through the heater core then back to engine generating heat for your heater system.
check both heater hoses under the hood with engine at running temp. if only one hose is hot your heater core is restricted( try flushing it out),m low coolant will also cause no heat since the heat comes from the hot coolkant in the heater core. if both hoaes are hot chances are the blend air door in the interior heat unit is faulty or climate control is not calling for heat.
Your heater core is leaking. This is the part of your car that creates heat for the passenger compartment of your car. There is no fix for a leaking heater core except to replace it.
Check for a heater flow valve in the heater hose they can rust shut easily it is a valve in the heater hose that opens when you turn on the heat and shuts when its not in use, if not then probably the core is plugged a radiator flush might help but you may need to have it cleaned and repaired.
The solar panels absorb energy from then sun, the solar energy is then transformed into heat energy causing the water to heat up.
Is your radiator fluid full?
The heater core is bad that's why you do not have any heat
To add humidity to the air as well as heat it.
your heater will be cold, or your engine can over heat. your car can take a long time to heat up. Your inside heater will be cool, or your engine temp. will over heat.
The water is not circulating through the heater core or you have a control problem. If the heater is putting out heat then it is probably a control problem. If no heat then - water pump out, low on coolant, or maybe the therostat is stuck open.
If you are not getting heat out of the heater, there are only a few things that could be wrong. The first is low coolant. You can't get heat without coolant running through the heater. If it is low, sometimes it has to be bled of air bubbles. If both heater hose running to the heater are hot, you have circulation. If not the heater could be plugged or not getting the coolant to circulate. There is also a damper in the heater system to stop cold air from bypassing the heater and that needs to be checked.
It is possible the thermostat has stuck in the open position therefor not letting the engine heat up. It could also be the heater core or possibly the hoses to the heater core are disconnected.
Feel the heater hoses in engine compartment if one is hot and other cool try flushing heater core.
it could be the thermostat needs to be changed or the heater core needs to be flushed out.these would be the cheaper things to try first.
low coolant? Bad thermostat? Climate control not sensing proper temperature? Heater core plugged or restricted? Heater core airbound?
My 2001 Chevy Blazer was blowing cold air when I had the heat on. My husband flushed the line to the heater core and a bunch of junk came out and now my heat works great.

How to remove the heat core housing on a 2001 crown Victoria? I remove the dashboard, can't get heat core housing out.
