Hello welcome to just answer I am master tech and will be able to assist you today.
okay well tell me what needs to be done to have heat.
lets start by moving the lever then if this moves the air mix motor is most likely the fault here
is there a valve that need to changed?
dont have a lever its push botton
well lets first do the first part so i know which direction to proceed
open the hood
look on the passengers side on the fire wall you will see 2 hoses going into the firewall
move the little lever and this will allow the heater to work.
then have some one move the temp from hot to cold and watch the lever and see if it works or not
you will see it when you look at the water valve on the firewall
have you opend the hood to look yet ?
once again its a push button with a round temp control
all that has been done that while i am talking to u.
ok so you opend the hood and found the part i have been asking about ?
the push button has nothing to do with what im asking you to check first
did you find the water valve and move the lever
and does the heater work now ?
no still blows cold air
is the car warmed up ?
yes just drove 5 miles
do both hoses feel hot that are going into the fire wall ?
temp gauge is in normal opertating area has all new fuids
ok both heater hoses going into the firewall are hot .
engine still running
blower motor is working and blowing cold air out of the vents
40 degrees outside and its 11 pm
the air mix door is stuck on cold
what needs to be done?
since you manually moved the lever to the hot position this should work
do any thine need to replaced?
when you move the temp from hot to cold can you see the levers on the center heater unit move ?
im thinking this might be a air mix motor or a blend door stuck
what is that?
this is the door that blends cold and hot air.
how do u fix it?
well this is why im asking if you can see the linkage moving
do you see the one that has the cable that goes to the firewall does it move when you move the dial from hot to cold ?
and i still do not have heat.
the reason i ask is these air mix motors fail all the time
i will have to check
the heater valve when open will allow the hot liquid to flow through the heater core .
how do we replace it and how much do they cost?
you replaced the coolant ?
these run around 80.00
did you bleed the system ?
is this a v6 or 4cyl
dealer item only
when you refilled the system did you open the bleeder valve ?
old hotrodder know a little bit. YES
ok thats good then
still need heat
this is odd something does not make sense
the water valve is open and both hoses going into the firewall are hot, the heater has to work
unless the flow is restricted or plugged but then the inlet or outlet hose would not be hot
its late and 38 degrees outside send it to my e mail and I will take a look in the morning. May have missed something in the dark.
ok lets continue this in the morning
Are east coast or west coast?
cal west coast
okay 12 my time 9 am yours. Dont forget to send to my email i will be out in the field using laptop. its 11:30 here
send ? maybe in the daylight something got over looked ?
did this just start after you replaced the coolant ?
i know the night does play tircks
so in the am see if the air mix motor moves the cable that goes through the fire wall
and see if all the linkage moves when going from hot to cold.
will do must have heat live in the south.
38 deg's and not heat is bad
yes very true
talk to you in the am
its in the 20's in the am. cool thanks
