Hey just wondering if anyone else has this problem? I have a 2014 GMC Sierra and just got 75,000km, the issue I'm having are the power windows just stopped working and when I open my door to get out the radio stays on. The other day I also turned my lights on because it was foggy and there was no indication that they were left on when exiting my truck. This issue is quite annoying. I've checked all 3 fuse panels and all the fuses and relays are still good. Dealership won't even look at it without $200 diagnostic fee plus I'm sure an expensive repair and I still feel truck is new...........thanks in advance
