Hello I have a 2007 GMC Sierra W/T, I bought it from the dealer almost 2 years ago with manual windows thinking I would not have the need for the power windows. Now I want to install the power windows but I would like some to know what is needed. I found a place that would sell me the interior door panels and the motors. If anyone could please point me in the right direction it would be greatly appreciated...Please keep in mind I would like to make it look factory.
