If a fuse blows then you have a circuit problem, this sounds like a cross circuit, I would start in the engine compartment and the first thing I would check is the power distribution box, look underneath for any burnt wiring or even a burnt box. If everything checks good there then it’s time to drag out the wiring diagrams and trace the starter and taillight circuits.
