You have a short in the circuit. Start by disconnecting the swithces in the center consol. then replace the fuse. If it holds and does not blow then connect one switch at a time. when the fuse blows at least you will know from what point in the circuit your short is located.
The wires bend a lot at the door hinge so this is a spot where wear occures. Also it is possible that the motor has shorted. BUT the switch woudl also have to fail at the same time to allow this. Highly unlikely.
does the fuse blow when the switch is installed or after the window switch is pressed. Which one?
If it blows when the fuse is installed does it happen when the center consol swithces are disconnected? then it is not the wire harness from the fuse box to the center consol.
Follow this concept and figure out when and where the fuse is blowing.

Since you posted that the fuse keeps blowing when you replace it. disconnect eh switches in the center consol. does it blow? if so then you will have to trace the wiring from the fuse box to the consol and figure out which one is shorted.
