the fan blows cold air and there is no heat at all, the windshield also foggs up alot from the inside, could the 2 be related?
If you adjust your temp control to the highest degree..then reduce to the lowest, you will open the baffle which is probably stuck..
A blocked heater hose could cause a leak. A stopped up heater core could as well. Or the connector in the Windstar could be cracked.
If you are absolutely, positively sure that your coolant level is not low......then your heater core could be plugged. Or the control that turns the coolant flow on/off to the heater isn't working. Make sure the control is working, the flush the radiator. Should cure the problem.
COULD BE A BAD HEATER CORE COULD BE A BAD HEATER CORE sounds like the heater control switch needs replacing.if that doesnt fix it, you need new heater core
If you have lost a sufficient amount of coolant this will stop the heater working because there will be no hot water in the heater rad.
Yes it could also cause the A/C to stop working.
There could be multiple reasons why a heater would stop working in a truck. There could be low coolant or a bad fuse to make a heater stop working in a truck. The best way to find out the reason is to take it to a certified auto mechanic.
If the air conditioner in a Mitsubishi Legnum is not working, there could be a blown fuse. There could also be a loose cable, or a problem with the heater motor.
You have to be more specific. What is not working?
heater core could be rusty and old or line to heater core could be plogged most likely old heater core
Could be the Climate Control Unit or Clogged heater core.
Check the thermostat, also there could be a heater core issue...
If the heat is not working at all it could be your blower motor. If the heat is no longer hot then it could be your heater core, or you could simply be low on coolant. Mine was low for me to find out that I had an intake gasket leak, fixed it and now the heat works great.
could be thermostat or heater fan if you can hear all the speeds on the blower motor working then it could be your thermostat but your heater core might be plugged as well
Could be low on freon,
Your car could be low on antifreeze or your heater core could be clogged. With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
That or the thermostat.
Could be your fuse, blower, heater core,loose ac belt, thermastatt or low coolant.
Blocked heater core, faulty heater valve, disconnected connection to the heater valve.
It could be steam from the heater core
a bad water pump could cause low heat. The heater uses the coolant from the pump to generate heat.
can be the heater blower motor resistor located in either the ductwork or under hood near blower motor on firewall
Feel of the hoses at the heater core. If one is hot and the other is cold the heater cont balbe is not working. If they are both hot, the mixing door inside is not operating. Make sure you have vacuum going into the cab from the intake.
Assuming the blower fan is working but it blows cold air, it could be,Faulty temp blend door actuator.Plugged up heater core.Faulty thermostat,Low coolant level,
It could be the heater valve which is located under the hood to the passenger side down below the radiator and fan units.
