blowing fuse 2004 c70
 

fuse 15 for interior lights keeps failing, and driver window switch does not work, fuse keeps blowing after short drive, window does work with 4 window switch, forces seat belt chime to continuously beep, assume short in door wiring since it chimes when ever key is in. any ideas on where short might be?

Unplug the window switch, replace fuse and see if it blows under normal driving.
