2004 Civic Poor Heating

Has anyone had experience with really poor interior heating in a 04
Civic ?

The thermostat is working fine, and the vents are blowing warm air
it's just the output to the floor is very low.

The dealers service advisor checked and said the flow was working fine
and that his civic was the same.

The heater is just not as good as in my older accord.

Any thoughts or ideas would be appreciated.

 

it was -35c here last week, and my heater seemed to be working just
fine...my feet were nice and warm

You have to drive it to warm it up . . . and maybe the '04 has a cabin
filter? I don't know about newer Civics.

it hasn't hit the -35 in Atlantic Canada yet... but if it does the
problem will be worse. Has the heater always worked well in yours or
did the dealer have to do something ??

In this case, as I mentioned, the car itself is at normal operating
temperature... all the "upper vents" provide lots of warm air, it's
just the ones for the floor that have little air flow and very little
heat.

Thanx

 

If you express an interest in a 2005 on the sales floor, you can test drive
one and see if the heater is better than in your car. If not, you can
believe the service advisor. Otherwise, he's got some 'splainin' to do.

Until you get the problem fixed, don't use the floor vents. It's my guess
that there is something inside the floor vents that is blocking or
interfering with the flow of the air. It would probably take a lot of work
and time to examine all areas of the floor venting system. If I were in
your shoes, I would just learn to live with the problem. Make plans to buy
a newer or new car in the near future.

(compare to subject line) - that would only leave the 2005 model, then?

 

I hear the 2025 model is much nicer.

Seriously, though, in the problem car it is quite possible the air mix box
is out of whack. I bet the car is under warranty and the service advisor
doesn't want to bother with it - he's hoping it will go away.

how is the 2005 much nicer? its exactly the same!

 

Mine was good right off the start. one thing you might want to consider,
open up your glove box, and take it off, there should be to clips holding it
on, directly behind your glove box will be 2 air filters. These filters
filter the air coming into the cabin of the car(so the air that hits you not
the engine) make sure they are clean, or perhaps just remove them all
together(the dx model just comes with the spot to put them, but the filters
aren;t there) That might get you some more pressure.

 

I mentioned the "2025" model, as a joke. Not a very good one, I guess.

Make sure you are not in defrost mode with the air condtioner on. On my
wife's 2002 she needs to turn off the airconditioner even in defrost mode
for the lower vents to deliver heat. It is a very strange system honda put
into the car that you have to manually turn off the air conditioner and why,
in below 20 degree weather, the air condtioner must come on is beyond me.

 

I have a Sunfire and whenever I put turn the dial to the defrost setting
the air conditioner light comes on! I don't understand - is the air
conditioning on or not?

 

Sounds like an air bubble block in the heater core or leading to the
core. Could be caused by a bit of gasket material. The core should be flow
tested to see if coolant is passing properly. This only seems unusual .. .
it can happen to any make.

 

Probably - although many cars use temperature sensors to deactivate the A/C
at low temperatures. The indicator may only be saying the system is
activated, rather than the compressor.

Turning on the air conditioner dryes out the air, so your windows will
defrost faster...
