following happens when i start the aircondition:
every time the radiator-fans start to work, you can see it in front of my honda. the lights get dark for a little moment.
and it's equal, if the car stands still with running motor or i'm on tour, maybe on free- or highway. in that moment, the two fans start to work, the lights get dark; only a second but it happens the whole time i'm on tour, aprox every 2 minutes...
and it happens only when i'm using the aircondition.
please help me.

Sounds like you may have a bad alternator. The alternator supplies electric current to your vehicle and when the air conditioning is turned on the alternator is unable to keep up with the electrical needs of your car.

What do you mean by interrupting? The lights don't go completely out do they? They just "dim down" a little! Have charging system checked out, the alternator may be putting out enough to keep the battery charged, and maybe even enough to keep the lights suplied with power , --but the a/c is another "draw", and may be more than the alternator is putting out! If so you will see changes of similar results, -When you turn on the "heater blower only" and other "hi-amp consuming items (with headlights on), - like a super stereo-amplified system (one like bulges the windows out when playing)! The lights will "dim" in rythm with the stereo beat too - (if you have one of these hi-amp draw radio systems)!They sometimes do, - even with "good" charging systems, (and require a huge capacitor to "level the "power draw" (keeping surges down to a minimum"!
Don't replace anything till you have the charging/battery system checked out, you may replace wrong part, and end up spending a lot more than nescessary!
Because you could have a "intermittent short" in comporessor clutch also, (which "blows out", ) and operates normally as soon as it gets going! In which case it might not be charging system at all!

Your a/c is pulling more power than it should from your electrical system 12 volt alternating, there could be several issues here one being your alternator not putting out enough , a/c compressor drawing to much - going bad, belt could be loose on compressor or taunter, or a short in your system somewhere. you can have your alternate checked for free, check your belts, if not have your electrical system checked by a mechanic, good luck

check your charging system, your loosing voltage to your lights this is why they dim. also check the grounds for your headlights, i would be willing to bet your fans geound in the same location and it could be dirty or loose. the fans pull the most power at start up. hope this helps
