I am looking to do my own window replacement on a 2010. Does anybody have some pointers i have read the post on removing the door panel but could not find anything on the window.

 

I've never done an HHR, but door glass is always a pain to do. Just take your time and look things over carefully before you start. The worst part of the job is working in the door where being double jointed with two extra hands would come in handy. Honestly I only ever replaced one piece of door glass before taking the car to a glass place for the other side. You may want to call a local glass shop for a quote since they do it all the time, you may end up ahead in the end by saving some frustration and time.
