I have a 2008 Nissan Versa. Over the past few months I have began to notice that when at an idle either parked or at a stop light etc. If I roll down/up the window the RPM lowers (usually about 200 RPM) and the engine vibrates heavily. Any idea why this electrical draw would do this? I do have bad engine mounts and actually am picking them up tomorrow as I had them ordered in but not sure why the window would do this.

Make sure there is no corrosion on your battery poles :-)
Clean them up and you will be fine

Just sounds like you have a weak battery.

That is indeed what happens when you put a load on the alternator. there's nothing concerning unless it does it while you're just sitting there or if your windows are really slow

I'm surprised the ecu doesn't contol this. Does the idle speed drop when you turn on the A/C?.

You may need a new battery. I recommend buying the ones at Nissan. They really are quality (surprisingly).

Just a quick update. I replaced my torque (Bone) mount on the upper portion of the engine and the lower engine mount. I also removed the battery terminals and scrubbed them down. Seems the issue has greatly improved and both of the mounts were torn. When looking for a replacement mount, walmart of all places had the upper mount on clearance from Motor King for $10.87!!
Thanks everyone

There are only 3 manufacturers of automotive batteries in the whole country. They are all just repackaged, labeled and branded at different price points and designed to different lonegricy points.

Probably can get the same battery for less without the Nissan name.

""As of May 1, 2013, there are three major automotive starting flooded battery manufacturers in the United States. There are four absorbed glass-mat (AGM) starting battery manufacturers and there are four flooded deep cycle battery/major deep cycle battery manufacturers in the United States.""

Would a " Nissan " battery be made in the USA or over seas ?

I have no idea but I'll make a couple of points.....guesses......most Nissans are manufactured in the USA, shipping batteries is difficult but making them here in the USA 🇺🇸 involves more strict environmental regulations.

So I have no idea.

Thanks to a little known search engine called Google Nissan batteries are made and branded for them by Johnson Controls.
