If I open my window partway down, then put my hand on top of it and push down hard, it'll slide down another inch. Other than that, the window opens and closes fine. If the window is completely closed, and I try to force it down, it won't budge, as expected. Also, this happens only with the driver's side window.

Is this something I can safely ignore, or is it indicative of a more serious problem developing?

 

bad window regulator.

 

What does that mean??? Should I be worried?

 

If you still have warranty, even extended Acura Care warranty, it'll cover it. I just had mine changed.
