USA car or NOT, ?????????? what engine?
with or with out electronics temp control options
I can't see the dash to go ahhhhhhhhhh
EATC for sure has named
bend door.
fuse are first are they all good>?/
below 120f coolant the blower is taken off line.
well there are only 2 causes.
one under the hood, engine not hot,. thermostat bad.
two, cam dampers failing. or heater core clogged up. inside.
a tech does simple tests to see which end of car fails
even a finger,test. to the 2 tubes passing the fire wall to the heater core. (ouch,ouch) test tube,1 and 2, are 180f to 220f hot that is good test for engine bay good
and the core is not clogged
if hot /cold is fingered, that is clogged up core.
the first question that pops to mind also is does the cab core have hot water valve. most cars now do not.
i just look at the 2 heater core tubes for water valve and even cable drive or vacuum drive to it.
there is vacuum servo called heater door actuator
or has below EATC
here it is and if dead and stuck in blend cold ,heat ends
what I do is 2 things, (working cab side)
core tubs both hot 180f UP
i watch all damper doors, actions in all modes.
3 or more.
if say blend door is dead, i move it by hand,
some even wire (bailing)wire it to hot and drive all winter.
until spring and fix it then.
yes one has vacuum blend door
and yes other model has gear/motor actuator EATC blend door servo./
what you, nobody knows
but id pull off all lower panels to the dash and look first
sure whole if core is hot, 2 tubes, sure would
hood up facing engine
spark plug 5 is center of the 3 cop coils bank 2
facing it 4,5,6(bank 2)
far side 1,2,3 (bank1)
