Okay, thank you. I'll check it out when I get home tonight. This is the only forumn that I found for "GMC" that someone has done the install. Nothing on the GMC/Duramax forumn. haha.
I have the same fuse number and components running off it, and the panel is the same as the picture provided in this thread. I’ll give it a try this weekend.I just went and looked at the diagram in the fuse box. It is #92 - Cool fan clutch/Aero shutters. hope that helps.
