I have a customer who has no dome lights in his 15 gmc 3500. He is out of town and I am trying to help him check his fuses but I cant find another truck to go look at. On a 14 Silverado it is Body Control Module # 7. I don't think they are the same. If anyone knows it would be very helpful. Thanks.
