Almost brand new Civic with automatic trans. When car is accelerating in
second gear, the air conditioner blows non-cool air. When it hits 3rd,the air
gets much cooler. Also ok in 1st and idle. Also, I think the air could be
colder when it IS cold... but that's another issue.

Is this "2nd gear, 'warm' air" a known issue with the 2004 Civic EX?

Thanks,

Al

On some cars the A/C is shut off during hard acceleration, don't know if
that is the case with your Civic.

What is the relationship of the accelerator pedal to the floor when your car
is going through the gears?

I'm NOT doing jack-rabbit acceleration. I'm talking normal "from a stop light"
acceleration in traffic. I'm not flooring it out if that's what you mean. I
guess I should look at the tach and see at what rpm the air turns warm. I
know it's in second because it gets colder when it hits 3rd.

What's goin' on?

That is an odd thing to have happen. I would call the dealer and tell them
about it. Perhaps they have a good explanation.

It isn't really. Most cars will drop the compressor at high rpm. If he is in
second long enough to feel the air to warm up he is dogging it too long.

I called the service dept. at the dealer I bought the vehicle from (car only
has 2500 miles!) He says this is normal for the Civic... that there is a
sensor that will turn off the compressor if the engine needs the power.

Do you think they are blowing smoke at me? I had a 1990 4 cyl. Honda Accord EX
for 14 years before this new Civic and never noticed the AC change from cold
to "regular" air and than back again while driving. Comments?

it's called compressor cut, and is commanded by the ECU. it happens
at lower rpm than the older model. it's very noticable on the new
civics . It's also normal.

If I had known about this in advance I would not have purchased the car. Do
all new cars have compressor cut?

Hi,
Old cars too. compressor cut off and rpm increase when ideling with a/c
on. It's one way of increasing CAFE as well.
