Check to see if your coolant is full, if it isnt fill it first, then check to see if your thermostat opens properly by feeling both heater core hoses after engine warm up....both hoses should be hot.......if not, a stuck thermotat or plugged heater core is the problem
...good luck,,,marty

Heater doesn't heat when cold

Chances are it is indeed the heater core as even a spent heater unit will blow hot air off the engine when the ambient temps are hot . When the temps drop, the heat from the engine block is not enough to heat the cab properly. Have you tried the old cardboard in front of the radiator trick? Speaking of semi's,ever notice they cover their radiators in the winter? That's because it helps get their block temps up a little higher and assists with heating as well. It's not much help but do the buyer a favour and let them know beforehand. Have a good one. :)

Installed a circulation heater in a 2003 Highlander, now very little heat in the cab

is there a check valve in the kit? I would have thought the flow would be to the heater core ,otherwise the core won't get hot water.

Toyota Tacoma heater will not blow hot air

-Check heater control valve. (The one open and closed water)
it should move when turn to hot or cold. If it move or turn.
-Next disconnect the heater hoses (Two lines) and flush with garden water hose from both direction for couple minutes.

You should be good for winter.

Why would my fan blow but not blow hot air?

Locate the heater hoses and feel for temperature.Should be warm to the touch.
There may be an external heater control valve next to the firewall that is either vacuum or cable controlled.
the lever on the side opens and closes: warm coolant going into the heater core,inside the cab. If the valve is stuck,no heat.
If the vacuum to the valve is ZERO,it should open.
If the heater control vacuum hose is leaking air,you should get hot air ALL of the time.
people in the winter want heat NOW. Bypass the heater valve,under the hood with a section of copper or plastic tubing.
Even if the heater core is partly plugged up,you will still get some heat.
If the control valve is stuck closed: NO HEAT.
Listen under the dashboard for a hissing sound.That may be the problem for the control valve not opening.(Turn the fan off)
I'll assume this is a late model truck.

After replacing timing chain in 89 toyota 22-re my heater hasn't blown very hot air. I've changed thermostat and flushed coolant lines. I used to have an awesome heater but now when I turn blower full...

yes a bad water pump will cause it not to circulate the coolant through the heater core,find your coolant leak 1st is it leaking into the cab on the passenger side of your truck? thats another sign of a bad heater core also.make sure that you don't have an air pocket in your cooling has to be full for the heat to work properly.thank you for choosing

88 Celica has no heat. AC works fine. Any ideas

the a-c and heater run on 2 different systems the heater needs coolant going thru the heater core to make heat by blowing air through it and the a-c uses it's own sealed system to cool the air so if you have no heat / it has nothing to do with the a-c working or not . first thing you do is check the cooling system like rad and coolant levels . you will have heater core hoses running from the engine to the firewall going to the heatercore . grab the heater core hose and feel if it's hot . if your hoses are hot then the heater core is bad or the blending doors are stuck .

No heat from heater, blower works ,fan works ,coolant good, pump good, luke warm heat, 1988

check the temp of the heater hose going into fire wall,make sure they are both the same temp,if they are replace the thermostat.
if one is hot and the other is not,the heater core is partially block and will need blowed out with air hose or replaced

My 2001 toyota tundra heater wont blow hot air. I checked to see if the heater core is cloged it seems fine the heater control valve is operating properly, and I changed the thermastat. and yet the heater...

If you've changed the coolant recently, it could be air locked in the heater core. To remove park the truck with the front higher than the back and remove the radiator cap. Start the engine and let it run while watching for a big air bubble burp coming out the radiator neck. Top off the coolant and continue.
