1 brake light out....turn signal switch?

Thanks. Yes, both signals work and as 67dart273 described. When I use the left TS and press the brake, the right brake lights up and vice versa. Whichever is the last brake light to light up is the one that works when pressing the brake only with no TS selected. Although, they both worked the last time so I left it for the night....LOL Good to end the night on a positive note.
Gotta be the TS switch. Thanks guys.
