Hey I have a 2008 Fit Sport A/T with about 22,500 on it. I posted in another thread in the tech section in regards to a vibration in the engine and airbox so I have been extra senstitive/paranoid about the way the car is running. I noticed the other day when I was sitting at a light that when I pull the window switches up (if the window is up and pull and hold both up), there is a pretty distinct noise and vibration. The can't feel the vibration but it is enough that the right wiper arm is noticably bouncing up and down, and when released, it stops. I highly doubt the two are connected and I know when this is done with the lights on they dim because of the extra draw. It is more of a curiosity thing than anything and wondering what you guys can make of it?

Oh and why I am thinking about it, did you guys get any feedback through the A/T shifter when you're driving and the engine and tranny are under load?

Thanks

 

It is your alternator putting a load on the engine, mine does the same thing when I roll up 2 windows at the same time.

 

Makes sense, I figured it was the alternator just didn't think it would be that harsh. Thanks
