No brake lights with passenger turn signal
 

I've tried searching but still not sure. All of the lights on the truck work, headlights, sidemarkers, taillights and blinkers. The problem is when I hit the signal to turn right the blinker flashes but my brake lights no longer work on either side. Turn the blinker off and the brake lights come on. This is pretty frustrating, any help will be greatly appreciated.

Sounds like a turn signal switch problem to me, I'm pretty sure the brake lights are wired thru the TS switch and something is not making contact in there.

Yes to that, Usually the off side brake light will work when you have the signal on but it looks like the contacts are too worn for that.
Switches are relatively easy to get but not fun to change.

yep, 100% right, time to replace the turn signal switch.
Odds are, your brake lights aren't working 100% of the time without the turn signal on either.
