    That's in the engine compartment right ?

    I changed it, and just changed it again with a 20 amp, and the power still did not come back

    im reading the owners manual and it looks like there are two fuse boxes.

    wheres the panel bopx. now I feel like a real noob

    pin#16 gets power direct from mini fuse#29, if fuse is ok and not getting power then you have problem with wire from fuse box to ALDL.

    I checked them and they all looked fine

    "Rear Fog/ADLD/TOP SW" ????

    Seems to ring a bell for me on some other GM vehicles.

    Exactly the same happened to me. Replaced fuse 29, back and working.

    What caused it was the following: Driving at night. My son connected the MPVI to the OBD II serial connection and I guess in the dark, didn't quite make it. There was a white flash and the fuse had gone. Is there some contact between the serial connection and the MPVI that would cause it to short? Is there a rule that says you should not connect the MPVI when the car is running??

    Tip for anybody replacing the fuse. The spare fuses are in the engine bay fuse box and the SPECIAL TOOL for removing the fuses is here, not in the passenger compartment where the blown fuse is located. Go to the engine bay fuse box first to locate the spare fuse.
