Why is my heater blowing cold


Most likely it is the heater control valve that shifts air from blowing across your heater core to your air conditioner core.

If your fan works and your car is fairly new..meaning your heater core isn't dirty and full of craap...then it is the climate cotrol valve.
If you are lucky, it might be a thermostat that is bad and blocking hot water from entering your heater core. Bottom line, if hot water doesn't circulate thru that little heater core, you won't get heat.
You might be able to look under the hood and grab the hot water lines that go thru the firewall and feed your heater core. If they feel cold to the touch after engine has warmed up, then you aren't getting circulating water to the heater core. If they feel nice and warm, then the heater core is fine, but your climate control valve has closed off the fan that blows across the core to disperse heat into the cabin

The heat does does not work in my 98 Tahoe at all its blows cold all the time I have done changed the there and put new coolent in it still have no heat so I by pasted the heat valve and ran it right in...


If you are getting hot water/coolant to the heater core and still no hot air coming out the vents, then it's a issue with the climate control or blend door. After running your engine and it reaching normal operating temp, locate your heater hoses that goes to the heater core. Carefully touch them to make sure both hoses are hot to the touch, if they are, you are getting hot water/coolant to and from the heater core. So, then it will have to be a issue with the climate control in the dash or either the blend door in the air box. It's a common problem for the climate control to go out on these models, hope this helps.

Your closing in. There is a motor that will open the heater core venting to allow it to blow into the car. Get a heater core install picture from your auto parts dealer or car dealer for specs of where and how it is driven.

My heat in my truck doesnt work


The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.
Flush the heater core 2-3 times, and if the obstruction does not clear, a new heater core is required.

2001 Acura TL Climate Control Blowing only Cold Air.


Ok it may be that the heater core bypass valve isnt opening. All that valve dose is when you turn the climate control to heat it opens a valve that allows hot coolant from the engine to flow through the heater core. What I would do is check that. It will be on the left side (passange) of your engine bay.You will see two black coolant hoses next to eachother and one will have a black box with a wire that runs to it. Have someone move the climate control from hot to cold to hot back to cold. If you dont see the wire move then you can move it yourself to open the valve.

Let me know if the valve opens or not using the climate control.

I have a 2000 dodge caravan, no heat


Sounds like the air "blend" door might be inoperable. This door opens and closes a specified amount to regulate the amount of either cooled or heated air, as requested by the climate control unit. If the door is continually in the position which is bypassing the heater core (cold setting), the air will not get warm regardless of the condition/operation of the heater core. I'd suggest having this component checked.
