my fuse keeps blowing everytime i turn on the headlight switch at night. ive replaced it with a higher 25 fuse and even a 30 the 25 pops and the 30 just gets hot and the lights do not turn on. i also replaced the headlight swtich and that didnt solve the problem. is it a possibility that it could be the aftermarket radio i installed. Would it matter that i did a tuneup afew days ago? Im clueless i need help.

When you replace the headlight switch did you check the loom? I had the same problem on my truck and the wire were melted together, remove the headlight switch and checked the wires.
