Well today after choking a bit with some smoke of my car while idling, I was observing the lights flicker and maybe I got it. I checked the A/C and of course the lights flicked and okay I turned it off. I then waited for the cooling fan to kick on and when it did, the lights flicked just as expected. I think just like our A/C system sucks in the summer, I think the alternator is a weak b^%h and can't handle any pulls including the cooling fan. Or maybe the fans itself pull too much oommmfff on the alternator. But then we face a baja with a strong battery then maybe this theory is wrong because the battery holds enough amps for every accessory in the car.
Please don't start bashing my theory because it is just an observation of my car. who knows but I am sure the dealership will never know unless we agree to pay the 89 bucks an hour to "check it".
