06 Limited 5.7 Junction Box

I am trying to find what I've been told is called the Junction Box. It's the fuse box under the dash at the drivers left leg. Based on bizarre electrical issues I'm having, a mechanic here has advised me that's the part I need but it's been discontinued from Jeep.

Anyone have a line on one?

Been calling, no one has a Commander. I've been told it's the same part from that year's Grand Cherokee, but haven't had luck yet either.

Confusesus;

Have you checked on E-Bay?

And as a last resort, I'd say try these 2 websites, maybe they still have some laying around;

See my article on the Junction block - right under the picture there is a parts reference to click on.

You've helped me before but I'm confused. Is the part you are showing in your pic behind the fuse box that I can see? The attached pic is the part I'm talking about and the one where when I tap on it, the Jeep seems to come back to life.

There's quite a bit of rust on that, looks like it has gotten pretty wet at some point in time.

It's not surprising after looking at it, that it's giving you problems.

The fuses are on the Junction block. The junction block is a circuit board about 10" by 16" and had 2 large plugs of wires on the side visible as installed, there is also a another plug of wires on the back side. On my link "Junction Block Explained" - click on the removal link at the very bottom of that post for better explanation and pictures.
Here is that removal document

rblapham - I've read over the materials you sent, and what I don't get is that I don't see an actual fuse panel in any of the diagrams like the pic I sent. I have a little drop door that opens to expose the fuses, is that fuse panel just lower and further under than the Steering Column Opening Cover, and that's why it's not shown in the instructions?

As for step 1, isolating the negative, can I just take off the negative at the battery or does it have to happen in the steering column as indicated?

And lastly, tapping on this fuse panel is what brings the Jeep back to life, so am I hoping that somehow it IS actually the junction box, and just my general banging around under the dash is vibrating something that causes a failed connection to make contact again?

Again, thank you for your responses, I'm doing my best to understand so I can either make the attempt myself or at least tell a shop exactly what I need them to do.

Scratch the previous post I pulled the lower dash out and now I totally see the part. Wish me luck!
