No air coming from vents


good the blower works.
it takes 2 more things,
1: hot water, (engine coolant ) at 180F or more holding.
if not fix that first.
2: water flow , if both heater core hoses get hot 180F then the core is hot. and means,
3: no air flow through the core,
dampers failing, or controls. to them.
tests

Air conditioner


sure.

what is your goal hot air, you never said,

got full fan speed? on high>? sure.
got full engine coolant heat 180F or more holding??? if not all is lost.
if car has a heater core water valve is it open>?
are the 2 heater core water tubes both fully hot,(hand test)
yes> good.
now you need air flow through the core (heater)
that means the damper most be open,, is it?

in that order. (heat)
the dampers on hondas can be complex. (10x on electric damper motors , aka, damper actuators)
see part 5 and 6 here

the fSM covers the complex tests of dampers, and not having
a real FSM makes this near impossible.
why , because your dampers are no like anyothers on earth.
other cars use different types. and are all unique .
unlike CABLES
unlike vacuum servos.
see>?

here are the basics for heat.

The heater core can partially plug (internally) causing heat from only one side of the dash vents. You can try to flush just the heater core itself, but most of the time the heater core asy requires replacement.

The heat in my honda accord blow warm air.not hot


sounds like you have one of two problems first check at heater core lines going into heater core see if they are hot if only one is warm then it could be the thermostat but honda's have issues with hot water valve cable jamming up this valve is located behind engine near firewall on one of the heater core hoses.

Cannot get heat even after changing thermostat in 1992 honda accord what do i check next


Check the heater control valve. It is usually behind the engine up next to the firewall. Have someone inside the car move the heater control to heat. A lever on the heater control valve should move when this is done.

This valve allows hot coolant to enter the heater core inside the car. If this hot coolant doesn't arrive, you have no heat.
