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.

Single mom. Kinda handy. This was the first post I read. Its 5 am. Getting ready for work in the dark. Thank you. Shes running!
Thank you!!! Probably saved me a couple of hundred dollars!!!
What was done to eliminate the 2400 fuse problem error code? Be specific.
