OBD2 Port No power?

[chevync]

Nephew has a 2004 Sierra Denali, the engine light came on but there is no power to the OBD2 port so I can pull the code? His truck went into limp mode and had to tow it home, I did the 10 second reset and drove it and it was fine. Any idea were the fuse it to the port?

put in new accesory fuse.. aka cig lighter fuse.. Its blown.

OBD port uses same fuse.. drop a penny in cig lighter, blow fuse, no power to port.
