Check fuses. (blower), could also be fan motor brushes bad. Check ohm's between both terminals, should have continuity, if so, check either terminal to metal housing of fan, if continuity exists, fan motor is bad.
heat not working
I think you have problem with the blower resistor. Please follow the procedure to check. * remove the connector to the blower motor. * use voltmeter to check the voltage. * connect one probe to the ground and the other probe to the 3.0R/w of the motor supply. * turn on the the blower motor with dial, you should read supply voltage, 12Vdc. * if you have positive voltage at the 3.0R/w then you should check the blower resistor and blower switch. blower switch supplies battery negative to the blower motor through the blower resistor. if you need further help please just let me know.
Your heating coils are most likely clogged.
Defective switch, resistor pack, or blower motor.
There is no heater blower is a Honda. The heat created on the air condition system is heated up through a heater core. If there is no heat coming out then the heater core will be the culprit.
First you have to see if your blower motor is working or not. If it is and still you have no heat then your heater-core is blocked and needs to be replaced.
Blown Blower Motor fuse, defective Blower Motor Resistor Pack, or a defective Blower Motor.
The heater blower may not be working properly. Without the heater blower working, the air will not come through the vents.
try the head gasket.
it could be the blower switch
it wont blow heat itll blow cold air
Check the blower motor to make sure its working propable
