The trailer taillights and vehicle taillights are on completely separate circuits so a fault in one system would not then cause a fault in the other on a 2005 Chevy Silverado 1500. If you have an issue with the left trailer brake signal then I also suspect you have an issue with the left trailer turn signal as well because these functions are both on the same circuit. I first recommend you check your fuse box for any blown fuses, the left trailer turn/stop fuse is in the center instrument panel fuse block which is located to the left of the steering column.

If the fuse checks out then you are then going to want to check the bulb inside the left trailer taillight, the ground wire on the left trailer taillight, and then if all else fails trace the yellow wire from the left trailer taillight to the trailer connector. I have attached for you a trailer wiring help article you may want to take a look at as well.
