So i have an 04 silverado, was doing some electrical work and i accidentally dropped a wire on the ground post and it sparked, next thing i know the truck wouldnt crank with the key unless i jumped the starter relay, the blinkers stopped doing anything, not even the indicators on the dash would light up, but the hazards worked, the tachometer was going nuts, and the AC compressor will not turn on, replaced and flashed the PCM with a new one and the truck finallt cranks and tach is back to normal, but the AC and blinkers still dont work, ive checked all ac and turn signal related fuses and all are good, freon is full and properly charged, what gives, also installed a new multifunction switch for the blinkers and no luck, any suggestioms are greatly appreciated

Do you mean that your AC isn't working at all or it still works but isn't cool?
