Auto Glass: window, wanda, pontiac

Question
I have a 2007 Pontiac the driver side door won't close. How do I know if its powered , if it has regulator. What could I do before taking it to the shop. And how much do parts run? Thanks.

Answer
Hi Wanda,

I need to know what model of Pontiac you drive before answering your question.

In addition, I would appreciate a more complete description of the problem.  I am not sure if you have a power window that won't close of if the door itself isn't closing.
