edgil1985 Posted December 19, 2011 Report Share Posted December 19, 2011 I'm having a small problem with my headlights dimming while idling and rolling my windows up. I don't have anything extra over factory except a grounding kit from Active Tuning but it was doing this before. Where would be a good place to start to find out what is causing this?

Rebel4055 Posted December 19, 2011 Report Share Posted December 19, 2011 Every car I've been in that has power windows I can hold and click the button when the window is up and make the lights dim and flash. I don't know why but it's very interesting what could cause it. Quote Rest In Peace mother.

Your amp is taking power. Do the big 3 upgrade and it will help. Get another battery or a Capacitor and it will fix it. I don't recommend a capacitor though, they just store power taken from the battery and use it where it is needed, which can lead to clipping. Plus, a good one that will do its job costs way more than buying just another battery. Edit: That is weird that rolling the windows up causes it to dim too, but I can bet money that getting another battery would fix that problem too.

blackandgoldl69 Posted December 19, 2011 Report Share Posted December 19, 2011 (edited) the reason rolling up the windows causes it to dim is its pulling alot of power to run the window motor. while also trying to power everything else. if you have a weak battery or an alternator that isn't charging to its full compacity then its gonna dim. get a multi-meter and see what your battery voltage is with the car off. also check what your alternator is charging at while the car is running.

edgil1985 Posted December 19, 2011 Author Report Share Posted December 19, 2011 So check the voltage with the car off and then start it and check the voltage? Quote Link to comment Share on other sites More sharing options...
