Puppies chewed through the cord on airconditioner in the window. I rewired color to color. It still is popping in wire fuse
Popping in wire fuse?  Is the unit actually connected to a fuse or some sort of breaker or tripping device. All AC units with cords that I know of come with a GFCI device at the cord cap. Is this tripping? If it is, pay attention to @EdBeals comment. GFCI's are very sensitive and you really don't have to have a short. You just have to have some sort of current leakage. 

I would recommend you try and order a new cord from the manufacturer or an aftermarket cord and replace the whole thing. 

Good luck.
