The first thing to check is the heater control cable: has it come loose, or broken? On the engine side of the firewall, you will find the heater control valve. It's got heater hoses from the engine running into it, and it's got a lever with a pin sticking out the side of it. Ideally, there should be a cable attached to the pin. There's also a clip to hold the cable's sleeve. If the cable's not hooked up, which I fear is the case, start by going in your car and setting the heat to "high." IIRC the cable will be retracted all the way. If it is, lift the lever all the way up, push the clevis at the end of the cable over the pin, and make sure the cable is locked into the clip. If it's all the way out, push the lever all the way down before you reconnect the cable.
Hose going from engine to heater core may have burst. Check all your coolant hoses for leaks.
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, low on coolant, stuck open thermostat, plugged heater core, temp blend door malfunction,
faulty control valve on heater or air in the lines
Low coolant and a clogged heater core are possibilities.
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.
If you are saying the heater is blowing out cold air you need to change the heater core which is located inside the dash
You may need to replace your Thermostat or your Heater Core.
no fuse check your anti-freeze level
did you check the heater core because my truck did that and that was what was wrong
Check to see if you pilot light is lit
because u pooped in it
Most likely your pilot light is out
It is because your heater is having to heat up so its blowing cold air out while its heating up.This means your heater is not very efficient and it needs to be checked.
Maybe its broken. Or maybe you pressed the AIR CONDITIONING
it is blocked and needs to be flushed out
it is your heater core most likey
You need to change your thermostat in the car.
The most common reason the heater is blows cold air on a 1999 Ford Winstar is a bad thermostat or blocked heater core.
either your heater control valve is bad or you heater control switch on your dash is broken pull the knob of and see if it is cracked.
Which part isn't working? Is it blowing air but it stays cold, is it not blowing at all or is it just blowing to the defroster?
Because you don't have enough coolant in your radiator.
it's old and you need to change it.
You should check the thermostat and the fuse for the heater.
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.
