In my GTA all my power accesories stoped working, my hatch release, power windos, mirrors,dome light,doors and horn...all at once. The radio, heat/ac, dash lights still work with no problems. I checked my fuses and they are all good. Any help fellas.

 

check fuses again....? sounds like you blew out the power window fuse, otherwise the power wire for them out of the fuse box went down and has a break somewhere
