I purchased a used chevy trailblazer ext 2006. The driver side climates control panel light just went out. Some say it is the ground wire (where is this?), some say it is a small bulb that needs to be soldered in. Also the rear lower white turn light went out, when I took it apart the socket was burned. I will get a new socket panel or. Entire light kit, just wondering if they are related, and how to get the Climate control light working. Thanks, Michelle
