Question about 1994 Acura Legend

Damper doors for heater

The car only blows cold air. Replaced the thermostat. The doors not opening to let hot air in. Think its the denso unit under glovebox. Do you know how to test it to see if it working. There was only one screw holding it up in place and none of the levers were attached. Please help. The car is an 1994 Acura Legend v-6 engine. Also, the a/c compressor stays on all the time. What should I do about that?

Another owner had the door stuck open (hot air all the time). You can remove the fuse for the a/c and see if the switch is bad (on all the time). The door solenoid may be electrical or on some cars vacuum operated. The a/c
compressor on all the time may over-ride the operation of the door for heat.

The heat started to only blow out cold air, replaced heater core an thermostat still getting cold air blend door is opening an closing as should


If both heater hoses are hot, then coolant is coming and going into/out of the heater core. The only thing that would affect heat would be a blend door not operating correctly. You will have to check the proper door that controls hot/cold air.

Car wont blow hot air heater


all cars... (otto cycle petrol /gasoline)
hot Air comes from hot water , in the engine,
so the first check is that the coolant does hit 180F and hold.
if not the thermostat in the engine is toast.
ok 180F , hot motor.
next ,some cars have a water valve for the heater coil
(alldata dot com, read the manual)
if the valve or its dash control to it is broken then it sticks closed.
other cars have no valve and they only block the core (bypass) the air to make hot and cold.
that too is a control. there are 3 types used, cable, vacuum and electric. on all cars.
what you have , is based on YEAR and options.
the book shows how to fix this. me ,just look at the controls.
if there is a cable then I make sure the cable works.
The heater has what are called damper, (flaps)
they open or close.
and if you have A/C more.
if the engines is hot. my guess, is the bypass damper is stuck
in the bypass mode. (fresh air only)

the best way to work on any car is RTM
you do that because these parts vary radically by year. and make.
alldata dot com is the solution , under HVAC.

Heater doesn't get hot on 96 chevy truck. Blows good, just cold. Replaced thermostat, flushed radiator. Any ideas?


Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

Why wont the heater blow out hot air in my 1995 pontiac bonneville. it will only blow cool air


If the heater hoses are getting hot, the problem may be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

2001 mitsubishi galant heter dont work blows cold replaced thermostat and radaitor still cold


There is probably some kind of damper that opens and closes under the dash that allows the air from the blower to be blow across the heater core under the dash. Sometimes these are controlled electronically or by vacuum tubes. Look underneath the dash and look for small vacuum hoses that might be dangling loose or possible little wire cables that might have come off the sides.
Possibly check Haynes Manuals (www.haynes.com) to learn how to change a Heater Control Valve.

My 92 for taurus wagon is blowing cold air instead of hot air, what could be the problem?


Behind the tempearture switch is an arm that is telescopic and raises and lowers the temperature. If this arm is either broken off or loose, it can create an inability to change the temperature. It can also be a problem with the heating unit in the ac in the car.

Front air blows hot air while back air is cold. Can turn it off and on and it will work for a while.


I have the same problem, when running the air conditioning the front vents will blow hot air. I have not removed the dashboard yet, but I think that the air damper is stuck in the open position. It seemed like a heater core valve problem, but I am pretty sure it is a damper under the dashboard. Now however, I am finally getting some cool air out of the airconditioning vents, but when winter comes, I am afraid I will struggle getting heat again.

Heater only blows cold air


Check both heater hoses under hood to see if they get hot, if they do the heater is fine. need to check to see if the selection doors inside the unit are opening and closing.
