    Hello, first thanks for any advice I may receive. It’s been a while.

    This is weird. The marker lights and inside dash lights stop working.
    All the fuses marked for light are good but I just notice that the heater control module fuse is blown and when I reset the fuse the lights come back on then the fuse blow again.
    What could be the problem?

    Those lights are protected by breakers F3-C (30 amp) and F8-C (15 amp). F9-D is the breaker for the heater control module which is the temp control panel for the sleeper. This is only rated for 10 amps. If F9-D is supplying power to the lights, then someone has tapped into it by mistake or because they didn't know better, but I would say it is something like this and the wiring needs to be traced to see why and then fixed.
