Power accessories drawing the juice

When I press the power windows, power locks, sunroof, etc. buttons my car drops in rpms, and the car shakes and rattles. What is the deal? Especially if the windows or the sunroof is closed and I press close and hold it down the rpms reall drop low.

Anyone know??

Mine does it too. I have a new alt and battery and all that fun stuff.

Even with the upgraded alt and battery it still does this?

i just got my alternator changed today, and it still does this. my only real assumption is the grounds. replace them, and it should help.

Yes. I dont care though. Its going in 2 months anyway. TC here I come.

Anyone else know anything?

I would also check the grounds,[ motor to chassis, batt. to motor and chassis] :cross: 94
