Hello,

I recently installed 4 new speakers in my 07 Honda Fit. My power locks don't work and my left rear window does not go up or down. The fuses have blown, and they blow quick after I replaced them. The motors on the other 3 doors work fine. Since the power locks do no work, I am not able to lock the hatch. Looking at other threads, it seems I have a short somewhere, but the wire harnesses look fine...any ideas?

 

when I screwed in the adapter bracket for the speakers, the screw when through the wiring harness for the power windows and shorted it to the metal door panel. The probability of that happening is ridiculously low, but if decide to install new speakers, make sure you find out the wire harness routing! I actually found it the next day after the problem, but I haven't been back to this site in a while.
