The blower motor quit working after a month of not wanting to shut off

what sub model accord, v6 LX ,
manual or full climate control option??? guess full.
fuses not checked PCM scanned for DTC errors EVAC, hopeless/?
so car starts and runs sand drives ok, <<< not told that.
yes the AC brain on most modern cars is BCM brain controls
and the brain does control the AC compressor. if that is dead so be AC, THE COMPRESSOR CLUTCH, is run by PCM RELAY.
NOT TOLD OUTSIDE TEMPERATURE NOR COUNTRY../
HERE IS A LIST.
1: CHECK ALL FUSES FIRST, CAB AND ENGINE BAY ALL FUSE BOXES SKIP NONE.
2: CHECK IP CLUSTER FOR ERRORS ,ALARMS ERRORS OR LAMPS GLOWING OR IMMO LAMP SHOWS IMMO IS UNHAPPY, MODE.
3: ENGINE STARTS AND RUNS AND CAR DRIVES.?????????
4: HEAD LAMPS WORK KEY ON AND OFF. ,
5: OTHER ELECTRIC FAILURES OR JUST THE BLOWER ONLY?
6: SCAN THE pcM FOR ERRORS, AC IS CUT DEAD EVEN FOR ENGINE OVERHEATING OR OVERLOADED !!! OR IN LIMP MODE/
yah can't fix modern cars lacking a scan tool, no way./

bLOWER FACTS
PER THE SM BOOK REAL

THERE IS A BLOWER RELAY AND SOME FUSES. 12VDC SIDE.
FUSE 30 DASH
AND 21 HOOD, BOTH MUST BE GOOD. and fuse 12 V6
THE bLOWER gets GROUND FROM THIS
Audio-HVAC--Display Panel
l AND ITS BLOW POWER TRANSISTOR MODULE
SO WE KNOW THE TRANSISTOR IS off. IS CAUSE 1.
ONLY WHY REMAINS!!!!
YES THE CONTROLLER DOES NOT WANT TO RUN ANY DEAD BLOWER AND RISK ICE DAMAGE TO THE EVAP CORE.

THE Audio-HVAC Display Panel, READS MOTOR SPEED ACTUAL. speed (a kind blower tachometer wire)
IF SAY A INSECTS NEST JAMMED UP THE BLOWER FAN
THE AUDIO -HVAC, MODULE SEE THAT AND CUTS AC DEAD BY DESIGN AND HARD GOOD REASons/
the THE Audio-HVAC , has the ICE up sensor and monitors R134a
high/low switch and if wrong, tells the PCM to shut down its
Clutch solenoid to compressor ending all AC .
I am no sure what blower does.
but I can say this tell of blower works in heat mode or blower + no AC no HEAT mode. yes then the blower is not bad, nor the controller
what is wring is inputs to the controller are dead wrong
and not scanning the PCM after fuses is why you don't know.

l;earn now this works

not checking fuses first then scanning the PCm is why answers simple are not found.

like these and scads more.

Sounds to me like the A/C clutch is no good and out of adjustment.You should goto your nerrest junkyard and get a used assembly take the clutch off then you learn how it comes off and install it on yours the save the pump for later use if needed. The clutch should only have a .010 air gap after install between th inner elctro magnet and the clutch plate it's self.

The MOST LIKELY cause of your problem is a bad blower motor. The next time it quits, look up under the right side of your dash and "thump" on the motor housing with your hand, if it starts blowing again when you do this, replace the blower motor.

NOTE: It would be easiest to go ahead and remove the lower trim panel from under the dash (even if the blower is working at the time) so access to the blower motor housing will be easy when it quits again.

I'm afraid you have the deluxe system,my friend. It has 2 electronic circuit boards that may be going bad. Very expensive unless you can find used or aftermarket.
I hope it's just the blower motor, but I had the other thing happen and I had to wire around it,losing my AUTO temp and blower control. don-ohio

The 'whirring' sound from the blower motor could be a dry bearing or damaged armature (part of blower motor that the brushes ride on), or just wore brushes. The smell could be the motor winding wires burning due to blower motor bogging down and overheating. You can replace blower motor with new or salvaged one.

CHECK AC / HEATER IGNITION FUSE IT WILL BE 10 AMP FUSE.CHECK HVAC BLOWER 20 AMP FUSE.HAVE BLOWER MOTOR HOTWIRE TO SEE IF BLOWER MOTOR WORKS.BECAUSE THE AC / HEAT CONTROL MODULE OR SWITCH COULD GO BAD WHERE NOTHING WORKS.

Follow the wires from the blower motor back to the blower motor resistor, normally only a few inches away and held in by a 7 mm screw. Replace it

Hi Adam,sounds like your blower motor resistor is bad,it controls your blower motor speed.Here's a link on how to replace,read the beginning and it will explain how the system works,as it says,their a different types for your vehicle so remove and take to Autozone and match it up with a new one. Repair Guides Heating And Air Conditioning Blower Motor AutoZone com Here's a link to some new one's. Blower Motor Resistor

This is more than likely just the resistor as a bad motor wouldn't start at all,And low refrigerant(Freon) has nothing to do with the blower.

Replace your blower motor relay. It's located under the hood on the firewall passenger side.
