i was looking at the window motor my bros friend installed on my bros car, and i just fixed the track for the window, it was messed.
when i reconnected the window motor, and neg batery post, when i turn on the key, all the interior lights start to fade really badly and the car doesnt sound like its gonna start tried once.  Sounds like when you double crank the car.  
What happened to the car? What does it sound like.
