    I have the same issue with my sons 2000 cougar V6. I changed the thermostat to no avail. I did notice that when I cranked up the RPMs in idle to around 4500, Heat began blowing out of the vents? No over heating and its got coolant. Any help would be appreciated...

    I have the same problem with a 2000 Cougar. No heat comes out of the vents. It blows cold air. I tried all the fuses, they are okay.

Heat does not blow onto windscreen but blows through other vents - whats wrong

What make an model an year vehicle do you have ? The air blows out of the floor vents an center vents but not defrost ? Possible mode actuator , stuck mode door ! There is a door inside the heater / A/C assembly that directs the air to the desired position . These doors can be moved by a vacuum operated actuator or an electric motor . Sometimes thing's put on the dash end up inside the heater box , fall through defroster vent ! Pens , pencils etc.. Depends on the make vehicle an system , manual , or automatic climate control . Some of the newer vehicles the HVAC system as it is called , the control panel is a electronic control module an can store DTC'S - diagnostic trouble codes !

My 2012 Chevy Traverse will only blow on the floor not upper vents or defrost.

the flipper in the dash won't change it to the other vents. maybe worn out. vents could be plugged. there should be something inside your dash that when you press the button or change the setting on the heat diverter it should switch from vent or floor. it's plastic and wears down or maybe jumped the flipper thing to move the heat thru the vent system

I have a 1999 Caddac DeVille . The AC works fine during the summer but in the winter it won't blow out hot air unless I'm driving. I've let the car run in the morning to warm up but the inside...

your heater core is possibly stopped up if there has been a radiator leak and stop leak has been poured its definetly clogged or could be a faulty thermostat

No heat blowing from vents already replaced

I had a problem with that in January 2008, my thermostat was fine. I took my car in to the dealer and they said the hinge that opens and closes the hot/cold air inside the dash broke. They had to remove my entire dash and replace the part. Luckily I was under warranty and didn't have to pay but the repair would have cost $3000.

My heater does not work,inside of the panel show well, botton up,

I'm not an expert, but I took my 2000 Lincoln Nav to the shop and they told me the issue is that my accuator is not opening properly to allow the heat to go through; therefore, it's overheating. That's why I can feel some heat on the front in the back. All vents, including the rear vent blows strong, but they blow very cold.

Unfortunately, I'm also having an issue with my engine intake manifold or intake gasket being cracked causing anti-freeze to leak out of my tailpipe and smell badly through the vents - even on defrost - so until that's fixed, I'll never have heat.

Two vents blow cold air and two warm air inside car although heat is turn on to maximum

check the 2 cold vents see if they r blowing out less on high than the other. check ur vent hoses between the vents it might be disconnected and only sucking in cold air. that will get u started on a sollution. some vehicles vent hoses tend to run out side the fire wall in the engine compartment.
