My fan motor was bllowiinghot only on high replaced the ac control module now doesnt blow at all. Is there a fuse or amplifier?

There could be a few potential causes for this issue. One possibility is that the motor for the fan is worn out or faulty, causing it to cut off at the highest speed. Another possibility is that there is an issue with the electrical connection or the fan control module.
Here are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check the fuse: Locate the fuse box in your car and check if the fuse related to the fan or HVAC system is blown. Replace it if necessary.
2. Inspect the fan motor: Open the hood and locate the fan motor. Visually inspect it for any signs of damage or wear. If you notice any issues, such as a broken fan blade or worn-out motor, it may need to be replaced.
3. Test the motor: Disconnect the electrical connector from the fan motor. With the car turned on, use a multimeter to test if there is power going to the motor when the fan is set to the highest speed. If there is power, but the fan still cuts off, the motor may need to be replaced.
4. Check the fan control module: The fan control module is responsible for regulating the fan speed. It is typically located near the fan motor. Check for any signs of damage or loose connections. If necessary, replace the control module.

If you are unsure or uncomfortable performing these steps yourself, it is recommended to consult a professional mechanic who can diagnose and fix the issue with your AC/heater fan.

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.

Possible fan relay

When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

If you have replaced the blower motor resistor block twice all ready, i would be replacing the blower motor itself. When the blower motor is drawing too much current it burns out resistors for lower fan speeds in resistor block, but doesnt blow fuse for fan. Also check for leaves and stuff in fan when removing fan.

Radiator fan or AC blower motor? The blower motor will have a fuse and a relay. The radiator fan is controled by the Variable Relay Control Module and temp sensor.... the module is located behind the grill---hope this helps.

One of a few things. First, check the blower motor fuse. Second, Check the blower motor Relay. (Switxh with a comparable relay from another source to eliminate this as a possibility

Likely either a bad switch or relay. I'd also probe all fuses(regardless of what they are for) with a test light just to make sure they have power at both ends of each (takes ten minutes and eliminates the possibility that you missed something there.)

change the blower resister module,if this doesnt work replace the control head

Sounds like the fan control knob has shorted out. You can check the fan "blower" relay and fuse in the engine compartment but you need to make sure the control knob is good or you will keep blowing fuses and relays. If your blower fuse and relay are good, then just have the control knob checked and replaced if needed.
