2005 G35 Base Sedan. Headlights and blinkers not working after removing the instrument cluster to repair the fuel gauge. I have checked all the fuses and rechecked all the connections and even replaced the switch; still nothing. Any help would be greatly appreciated.

 

I can practically guarantee you didn't plug in the turn signal switch properly when you reassembled the column. You removed it when you took the cluster out.

If you did this work with the battery still plugged in then you might have fried something else.
