heater core.jpg
8KB, 255x197px
my car is a 09 honda accord 4 cylinder and it has little to no heat. i dont turn it on until the car is at operating temps. when i do all i get is warm air. but if i turn on the air recirculation button i do get a nice heat. without pressing the air recirculation button the current heat is dull.

i flushed out my heater core 3-4 years ago when i changed the coolant too. i thought the heater core was clogged but it wasnt. is there a scan tool that can tell me what is wrong when connected to the car? do i have to change the coolant again? please help

Well if you changed the coolant that long ago it's time for another change. Could be thermostat stuck closed or there might be a broken valve that allows water into the heater core.

>Could be thermostat stuck closed
my CEL would have came on if it was

>broken valve that allows water into the heater core

explain please

> coolant that long ago it's time for another change

okay! i thought coolant lasted for 100,000 miles or so. my honda only has 65,000. i think i changed it when it had around 40,000

>>16585491
coolant should last 30-50k miles
if it's still bright green it's good
old bad fluid will be piss yellow

>broken valve
he means that if the valve that lets hot coolant into the heater core isn't working you won't get heat
some vehicles have strange proprietary core designs that don't use valves or have integrated thermostats however
volvo and ford come to mind

it could also be a broken blend door or actuator

>green in any car
Yeah if you're a poor fag.
Oem blue Honda coolant or die.

>>16585523
so its best that i should just change the coolant and blend door? the part is only like 20$ on rock auto. what else could it be right?

learn2bantz tripfag
>probably likes dexcool too
absolutely disgusting
t. it's so easy being green

>>16585560
I'd assume, since you have troubleshot out the thermostat, the heater core and the blower fan
>$20 part
worst case, you have a spare part you can sell on CL
>>
>>16585591
Hate dexcool
Hate American cars.
I only use oem coolant
Green is seriously for cucks.
Am namefag not tripfag new friend
>>
>>16585591
the thermostat is fine because its not stuck open or closed. CEL would come on if it was

the heater core is not leaking or clogged

and my blower fan works i think because it still blows at all speed settings

so it should be that blend door. i'll change my coolant either why. thanks for you help anon. are blend doors a easy replacement? the part looks like only 2 bolts and a electrical connector

>>16585613
yes, it's a huge pain in the ass that varies widely from disassembling the dash to removing components like the ECU, look up a video on youjewbe and check the forums for the proper instructions

Don't depend on a light. Check your coolant level.
