2003 Dodge Ram brake lights

The rightside brake light went out and I changed the bulb. Now my brakelights don't work at all now. I've checked all the fuses in the engine compartment, and even changed out the brakelight switch and they still dont work. On the dashboard, it still says "lampout, " but I dont know what else to check. My headlisghts and taillights still work but no brake lights? Is there another fuse box or anything else to check?
