Hey y’all, ive got an 05 escalade with some brake light issues. At night the two flanking brake lights illuminate -not a bulb, or a fuse- but when i step on the brake, only the third brake light on the top of the car illuminates. I figured the brake switch was the issue since all fuses and i’m fairly certain all relays are intact plus my cruise control doesn’t work. I replaced the brake switch just now, which was a pain, and no luck. I’m stumped and at the end of my youtube mechanic skills. I would greatly appreciate any tips or advice, thanks.

The two outer bulbs are probably 2-filament type and the bright - brake - filaments are burned out. Common.
If the center "high mount" works it wasn't the switch............
