Suburban Electric/Start Problems

[bretcopsey]

I have a 1999 2500 4x4 that has had some problems lately. I'll start from the beginning to hopefully help narrow this down. Many months ago I heard a "clicking" under the dash that coincided with the interior light coming on and off. I culdn't immediately figure it out and simply pulled the light fuse. The lights quit coming on but occassionally it would sound like a midget was tapping out morse code under the dash!

A few weeks goes by then I start having starting issues. I ended up replacing the starter solenoid and at the same time I removed a remote start system that had been installed by a PO. I didn't have any of the necessary remotes, documentation etc to use it anyway and figured it could be contributing to the problem. I had hoped that this was the source of the "clicking."

The truck started fine again, and I also had interior lights functioning as they should. But soon after the keyless entry remote no longer worked, and the interior lights didn't function properly-this time not coming on with the door being opened??

Then, I noticed what sounded like an A/C compressor bearing going bad upon initial startup, but not every time. I finally realized that the noise was coming from the starter not disengaging.

Today I replaced the starter. I had a somewhat drained battery so I had it charged-it's only a few months old.

I went to hook everything back up, and decided to try a trick that was mentioned in another post on this board. I connected the positve cable, and connected a test light to the negative cable and negative battery post. The light came on and based upon the other post this is indicative of an open circuit.

I pulled every fuse in the dash, one at a time, and the test light remained on. I then did the same on the under hood fuse panel. Pulling the horn fuse made the test light dim, but it never went completely out. Then all of a sudden I heard that "clicking" again under the dash. I didn't find a midget so I started poking around I found what I am guessing to be the body control computer making the noise. I placed a couple fingers on the side of the "box" and could feel that it was the culprit.

Is this "box" controlled by a relay somewhere, or could the "box" itself be bad???

I'd really appreciate some advice on this!!!
