Need some help.
2008 Gmc Sierra 1500
marker lights won't shut off. if I pull the LT park fuse that side goes out. when I pull the RT park fuse that side stays on. if I unplug the right rear lights the front stays on, now I just tried the ground connection right behind the driver side front tire (which has power for some reason) lights go out but the back up light stays on.
Thanks
Al
