Air conditioner won't work except for defrost

The air conditioner for my 1998 4 cyl Accord will only work only in defrost mode, and blows out cold air. As soon as I hit the button for any other mode (defrost and vents, vents, floor) the air conditionling light turns off and it just blows outside temperature air. Does anyone know what may be causing this? Thanks

SOURCE: 1998 Mustang - AC blows only through Defrost vents

You probably have a vacuum leak on the passenger side. its a small plastic hose some times they come unpluged from the engine. or brake.

SOURCE: Dash vents will not blow air. Defroster and floor vents blow fine.

Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.

SOURCE: Jeep AC blows cold air at defrost and feet but not through vents

There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

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
http://www.hondaautomotiveparts.com/auto/jsp/mws/prddisplay.jsp?inputstate=5&catcgry1=ACCORD&catcgry2=2002&catcgry3=2DR+EX&catcgry4=KA4AT&catcgry5=HEATER+UNIT

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 air conditioner on my 2009 Ford Crown Vic PPV blows cold until accelerating then changes to defrost. If it is a vacuum leak, how do you find the leak?

The mode door and mode actuator change where the air comes out. It's operated by vacuum. So you either have a leak or a bad mode door actuator motor.

My 03 Ford ranger's air conditioner blow cold air but it will only blow on defrost, it wont blow out of the vents

your controls for floor,vent.defrost ect. is in default mode due to a loss of vacuum.
you need to inspect vacuum lines for being lose cracked,or disconnected.hose will run from engine
intake manifold through firewall into the dash.i'd start at intake manifold looking for bad hose

Defrost not working well, amount of air blowing is low. Acts like a blockage problem, all other parts of the heater system works fine.

While in defrost mode press and engage a/c button on dash(leave in hot air position) and see if that helps with defrost issue. What this does is with a/c operating it removes moisture from the air in car which is all fogged windows are is humidity build up.Dont worry cold air wont blow through vents even though a/c on due to position of hot/cold adjuster.
