am I wrong? on the flipside is cabin recycled better to use when using AC?
It uses that cabin recirc. mode when it has to get a hot interior cooled down the quickest. LIke mine, when the car's been sitting out in the sun at work all day. When I first fire it up and head for home it's on cabin recirc. but as the cabin temp gets closer to the desired set temp it automatically turns cabin recirc. off and goes to normal.

Okay - I put on the dome lights while operating the climate control and, yes, I did notice that the interior light did slighly dim when the compressor cycling started. Wonder why it it affects the dome lights, headlights, but not the instrument lighting?

Don't know Mike, but I'm really glad the instrument lights don't dim, that could be real bad! I think of the dimming as a "wink"

The reason the lights dim is because the compressor puts resistance on the motor, and in turn slows down the alternator. The ECM should bump up the rpm to compensate, but starting the compressor will almost always cause the lights to dim. The reason your gauges don't dim is because they have circuitry to keep constant current flowing, that way the "motors" driving the needles are not affected.

This happens on my EX 4cyl model randomly

I can be driving on the freeway and it randomly occurs, i notified my honda dealer and he didn't know anything about it.


I can have all my settings normal and all sudden flicker.

Folks this flickering of the headlights has been going on since the 7th gens came out in 2003 that I'm aware of. Now the dome light flicker I haven't heard of before but the rest is old news. Don't worry yourself silly over nothing. Yes, mine does it too and I don't like it but that's just the way it is. I hope someone figures out a workaround but so far it's just considered the nature of the beast and continues in the 8th gen.

You would think that if people have been complaining about this since 2003 they would have fixed it 4 years ago, but it is stil a problem in a brand new car. It's kind of dissapointing, but other than this, I am extremely happy about my car!

the only fix is to rig up a relay harness for your headlights...thats the major thing everyone hates....so if you make your headlights draw power straight from the battery...it will be fine

How would you suggest doing that, and would it fix the interior light issue also?

Don't be so sure about that unless you tested and the light voltage was below battery 12.7v. The "running" voltage is like 14.5-15v all regulated electronically by charging system.

I bet what happens if you ran some tests the voltage does like 14.5>13.x and you see the flicker until alternator regulator kicks in to readjust it (stabilize it)
I haven't check honda's but most cars draw power right from a main distribution power block/fuse that comes right off the positive of battery.
I personally am not bothered by the split second drop, I never notice it much while driving .

Me too. No big deal. In fact, had others not raised the issue, I may have never noticed it.
