I had to jump start my car last weekend. I let it charge back up before I drove it again. However, since that occurrence i have noticed that if I'm driving or stopped when i roll up the windows the interior lights and headlights will dim, one time to the point that it looked like my fog lights were going to cut out. I went to a shop yesterday and and they said I needed a new battery so I replaced it. The lights still dim when I'm rolling up the windows but not as badly as they did before. Is this dimming normal or should I be worried?
