The last couple of days when it has been cool at night I've had some weird experiences with my headlights and interior dash lights. Yesterday, my headlights worked but my dash lights didn't. This morning the situation was reversed. At noon when things have warmed up, my headlights work again, but my dash lights don't. I have aftermarket gauges in their own panel, The guages work, it is just the light circuit. They are connected to the lamp jumper on the fuse panel. The fuses appear to be good.
