I was just wondering is it normal, if when the windows are closed at night and you hold the window button up to close them (even though they are already closed) and your headlights/gauges dim for a second?

 

i get this too, i have even replaced the alternator with a 180 amp, but it still does it not that bad but i can hear it in the stereo since i have ground noise but yeah i see it too not that bad but i can see it when i hear it over my noise

 

Yes it's normal. Don't do it too often as it causes undo strain on the window motor assy.

 

yes its normal, just a power drain

 

its not power drain superj721, it means he needs more power to his electrical equipment, once it starts it gets worse over time, buy a 180 amp alternator an youll be fine
