Hello,

The first thing you should do is remove the interior light bulbs, I have seen the bulbs melt causing a short. Can you please shoot a quick video or images with your phone so we can see what you are talking about? That would be great. You can upload it here with your response.

There is a voltage drop at the fuse box. Fuses tend to blow out under load and the lights themselves do not blow and when the voltage drop occurs the lights go out but they do not blow. The fuses governing the interior lights on the other hand do tend to blow. All relays are good.

I would start by checking the bulb sockets. This is where the problems occur nine times out of ten. Can you upload some pictures of the bulb sockets?
