Ji553r Posted June 9, 2010 Author Report Share Posted June 9, 2010 bad window lift motors. rear ones are new and they cause the most dimming. with the front its slight but with the rear its like having a system hit with no upgrades Quote I don't fuck around.

dugee81 Posted June 9, 2010 Report Share Posted June 9, 2010 window motors do require a little power, at least for me. Try rolling up or down all four and watch the voltage faaaalll. I had a sonata, upgraded alt, big 3, 3 new batteries, still had headlight dimming. Now I have a pathfinder, upgraded alt sitting at 15 volts, big 3, 3 batteries, and I still drop down to a solid 13 volts when rolling all of my windows up or down. I don't think it should be an issue.

etaks_crew Posted June 9, 2010 Report Share Posted June 9, 2010 Well if its just the wiring for the motors then subs shouldn't hurt I would think. I wanted to put some 10's or 12's in her trunk but had doubts on her electrical when I noticed this. Quote Link to comment Share on other sites More sharing options...
soundzright Posted June 10, 2010 Report Share Posted June 10, 2010 just get the alt and battery checked, most places do this for free or minimal charge. Quote Link to comment Share on other sites More sharing options...
Wastehog Posted June 10, 2010 Report Share Posted June 10, 2010 It might be that your connections on the window motors are corroded or bad. The newer motors would use more current, because they use more power, because they are newer. A good reason why they use a lot of power is because the power wires are small, so they don't go up fast. I know the ones in my truck are like 14 ga wire for a decent powered motor.. which is kinda small but they work so.. that's all that matters.
