headlight fuse... blown... three times!!! HELP!!!

[omegahunterbass]

Hey. I have a 1993 Nissan 240SX. I have a random weird issue. My passenger headlight blew through three fuses... i cannot find why this is happening... originally, i discovered that one of the previous owners used a 20 amp fuse instead of the 15 amp. i replaced the 20, which worked for two minutes. I put a 15, and it burned immediately. Help, plz!!

what happens when you replace the fuse with a 20a? im thinking that maybe there is a short to power which required the 20a fuse, and then when you replaced it with the 15a fuse, it worked for a bit before blowing, and the next replacement fuse blew because now what was a short to power is a short to ground.

in laymans terms --- investigate the circuit and see where a wire may be melted or touching another circuit.

the 20a fuse is the one that lasted... i tried a 25a but it did nothing. It lasted less than the 20a
