If you will check the BCM like Jpbroad1970 suggested, maybe a simple reset (battery disconnection) would help?
Maybe is just a poor grounding. If you have a multi-meter you can check for yourself. One contact on the bulb holder has almost no resistance to the chassis. The second should have the battery voltage (~ 12V) when the brake pedal is pressed.
What about the third brake light (it's a LED type) does it works? Sometimes they are connected to the BCM but I'm not sure how it is on J. It would be worth checking this out as well.
