Thermostat stuck open or heater core clogged. Bad radiator cap or small hole in cooling system.
One reason your home electric heater is blowing cold air is the heating elements are burned out. A bad thermostat may also be the problem.
is the blower motor running? or is it just not blowing hot air?
Get a cheap volt-ohm-meter (VOM)at Radio Shack. Learn how to test voltages or ohms.
What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
could be head gasket problem. does your heater work? might need heater core , clogged up. do compression test. or bypass heater core and see if that works.
Depends, Is it blowing air at all? If not then could be the fan, fan motor, or an electrical problem possibly with the heater controls. If it is just blowing cold then your going to want to check the heater coil, on that truck I believe it is on the passenger side under dash/floorboard. you may smell anti-freeze if so the heater coil is the problem.
Sound like your heater core blew out on you
Blower motor, resistor, wiring or control problem are common causes
Change your thermostat. Mine had the same problem and it was stuck open.
No one knows if:The heater is NOT blowing - or blowing on high speed only, or... The heater IS blowing, but the air is NOT hotEither way, the "Related Questions" below will get you started

Same problem vectra heater only blowing cold checked water coolant and it was empty. Topped up now blowing hot just hope I not got head gasket probe
in my experience it is a slight leak in heater core it will be antifreeze causing this replace heater core and problem will be fixed
I am having the same problem.. I have already had to replace the intake manifold gasket cause it was leaking, still no heat. We will be flushing out the heater core to see if that's the problem. I may have to replace the heater core, we will see.
I assume your car heater is blowing cold air, when the heater is on. It seems that, you have air on your coolant. that air pockets blocks the cooland to travel through your heater. it may be a sign of a bigger problem such as blown head gasket in the old cars, such acura legend
faulty control valve on heater or air in the lines
If your heater is a heat pump , then yes.
Low coolant and a clogged heater core are possibilities.
Dodges are good for blowing fuses. If that is not it, the fan switch might need replaced.
If you feel no air blowing at all (when you are not moving) then your fan is not blowing. If it is blowing air, and it is cold, when the heater is on, then most probably your heater core is leaking, or is clogged. These are easily replaceable and go bad all the time in older cars.
Could be a bad thermostat or heater core
You may need to replace your Thermostat or your Heater Core.
You can avoid that problem all together with a gas heater like Desa International GWN30TA Vent-Free Gas Space Heater
