so the blower is dead just , ?
the blower does not blow to all vent ports in all modes
for sure recirc mode. (off fresh is 60mph path see?)
blower hear first, and on HIGH is best test, if fails only on low speeds the blower resistor block is shot.
must blow on high.
heard and FELT parked. key on, hot or cold engine.
its just a blower DC motor 12vdc, and loud.
all vent tested not just one and try all vent path modes,.
felt blow.
this is only 1 test of vast.
we do the tests serially, from easy (hot) to hard (cold)
step 2 if heater tests
in the fusebox. there is no such thing , its fan fuse.called blower.
if the fan blow hard, and there is no heat in any register using
recirc mode, and all vents. then the engine coolant is too low temp.
back up one post and read.
yes, check coolant temps for over 180f+
if too low that means the engine cooling thermostat is bad. (usually) but are you in Alaska or key west. that be big time useful .
you mean low heat. at all ducts with full fan speed and blows hard,
here is the correct order.
1: engine at 180F or more holding, a absolute must.
2: fan runs at full speed on HIGH, (sounds like it)
3: fan actual blows (felt) at full speed, to any vent, try all vents.
4: now heat, will happen, if not, the dampers are closed or wrong.
damper can be complex on newer cars,they have motor controlled damper servos';
is this just blower fan dead? problem. on high, if yes say so.
Check antifreeze level, if it is low coolant may not flow through heater core. If coolant level is ok feel the heater hose with engine running at normal operating temp and heat on high, if one hose is much cooler than the other you have a bad heat control valve or a pluged heater core.
it's either a fuse or it's a bad blower motor, it could be a bad blower
motor resistor but usually you'll get either high or low only, so if
you have nothing on any speed, high low etc, and all the fuses are ok
chances are it's your blower motor.
