Why does the new fuse keep blowing?
start looking at door connections and interior o head light for short
I would suggest that some were in the interior light wiring there is a bare power wire shorting out against the metal of the car, or a pinch wire in the light its self. This may not be easy to find and you may have to let an expert look at this.
Electrical short...
you have a wire shorting out someplace in that circuit.
you have a bare wire touching metal somewhere.
