First check to see if theres even enough coolant in the car first if ther is get a buddy to turn the temp to hot then cold from inside the car while you watch the heater control valve it sits almost directly on the fire wall it is connected in line on the inlet heater hose and has a cable connected to it see if the cable moves when your friend moves the control knob if it moves your problem could be in the blend door motor or control head if the valve is the problem it is pretty easy to replace just take your time to bleed the cooling system of air after the repair

Look under the hood behind the engine while someone moves the heat control knob. This thing moving is the heater control. Move it manually to free it. Or adjust or replace.

Heater is only blowing cold air

1: if engine not hot 180F there will be no cab heater.
2: fan must blow, it seems it does.
3: the mode switch must be in heat and the lever to max heat.
4: heater valve bad or clogged.
5: heater core insides clogged, (no coolant service every 2yr)
6: outside of heater core packed in leaves or pin needles.
7: dampers set wrong. in heater box.
8: controller of damages , bad.

do you want me guess, or to recommend tests.

Heater blows cold air for 20min then blows hot

There are a few things that can cause this problem. Reason #1 a low coolant level can cause the heater core to receive less coolant flow hence causing the heat to come less quickly. reason #2 sticky heater control valve, if this control valve is stuck closed coolant cant enter the heater core hense wont heat up the cabin, reason #3 clogged heater core, over time some heater cores will clog up even sometimes start to leak in cabin. All these are normal circumstances and should be checked. Good luck

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.
