My olds puts out hot air and sounds like its pulling in enough but when it comes to blowing it out there is a problem. my windows are all frosted as a result plus its cold. even after driving on the highway for a good trip and back home will not warm up. problem is way worse when its lower than -20. please help.

you need to have the system check for pressure-it should be about 17psi -if it goes higher you have a blown head gasket which is blowing the coolant out of the system-or you might just have a radiator cap which is failing to hold pressure-up to 17psi- also youmay not be getting all the air out of the system and have an air pocket which will get super hot and steam the antifreeze- have the system vacummed down and the antifreeze will be sucked back into the system eleminating the air pockets-so you have a few things to look here-Ihopr this helps-Denny
Heater core sounds clogged take the two heater hoses off (usually easiest on eng side) just put garden hose pressure thru both sides till comes out clear reconnect hoses top off antifreeze... Hope this helps!!!! Good luck!!! Remember if the car is hot there will be pressure on the hoses!!!!
you can try blocking the radiator with cardboard. the heat comes from your coolant so if its not producing enough heat you either are not getting the truck hot enough or you have a clogged heater core.
the simplest fix is to check your coolant level, if the radiator is low enough your heat wont come on. when the car is warmed up, switch the engine off and check the level in the over flow bottle (located on the passager side) first squeeze the upper radiator hose with a shop towel to check for back pressure. if theres too much pressure wait for the engine to cool down longer. using the towel again remove the overflow cap, the bottle is pressurized so do so slowly to allow any stem to escape without burning you. if the coolant bottle is low, topoff with DEXCOOL (GM approved coolant) once bottle is at the 'full hot' line replace cap and start car back up and switch heat on high/defrost. odds are decent this will fix the issue, and it will only cost you a bottle of antifreeze :)
This is pretty common with a leaking head gasket. The heater core collects the bubbles as the coolant passes through it until finally it's full. When you take off the motor turns faster and the water pump makes enough pressure to flush the bubbles on through the heater core to the radiator tank where they end up going into the coolant recovery tank. Watch the coolant tank as you pull the throttle open sharply, see if you see bubbles in it.
If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox
Is the air actually blowing into the car?But it's just hot?It sounds like your blower motor is not turning to blow air.you have a fuse,check the switch that controls the blower,and the blower motor it self.
did you cheked if there is enough refrigrant ( freon ) in your tubes by measuring the pressure . if there is you may need to check your condensor its may be clogged and not letting enough air comes through to cool the refrigran
hello , sounds like an air lock in coolant system , drain system and re fill very very slowly , if you think you are filling it slowly enough slow it down even more , also replace thermostat to ensure its opening and closing properly , hope this helps
It's possible you are not getting enough coolant flow to your heater core. Try pulling the hoses off the core, blowing it out with air compressor, fill with water and blow out again. Try this about five times and see what happens. Alot of times these cores will plug up or have restricted flow. They will blow warm at low speed but it won't flow enough hot coolant through to stay hot on high blower speed.
