In the 2015 GMC Sierra, the flasher relay can be located in the fuse box. To access the fuse box, look to the left of the steering wheel for a small seam or crack along the dash. You can use a screwdriver or prybar to open this panel. Inside, you'll find various fuses. On the back of the panel, there should be a diagram indicating the purpose of each fuse. If the diagram is not there, you can refer to the owner's manual for the vehicle. Once you've identified the fuse you need, simply remove it. Check if the connecting strip between the two raised sections is intact – if it's broken, the fuse needs to be replaced. If the strip is intact, the fuse is good and can be reinserted. Replacement fuses typically cost around $10, making them affordable.
