I have an Entegra 24B. There are map lights in the cab above the driver and passenger shoulders. These lights will not turn on with the attached switch. Neither the headlight switch nor the dash dimmer/internal light roller switch have an impact on this.
Sorry for late reply but just wanted to give the resolution in case it can help someone else.
As was suggested above, both bulbs were burned out, straight from the factory! I replaced with Sylvania 168 bulbs purchased at Autozone. Works perfectly.
