So only my third brake light and right hand side brake lights are lighting up with brake pedal depressed...Sometimes... Other times, they all work like a champ. After changing the bulbs, this still happens. I'm thinking i might have a bad ground possibly? Seriously i stink at troubleshooting when it comes to wiring. I don't even know where to start looking. Any ideas?

It could be corrosion in the socket or weak spring tension. Scrape and clean the contacts and check the spring tension where the bulb makes contact in the socket.

Rear sockets ground get loose. carefully bend the ground contact.
