I recently purchased a 2017 GMC Terrian and we are really happy with it. I replaced the tail lights with LED bulbs but as you are aware, caused hyper flashing. So I did a search of both fuse panels (under hood and passengers side) and no luck. I am thinking the Flash Relay might be under the dash near the steering column. Any one know where it may be located?
Thanks for your help.
