Dash lights fuse keeps blowing
Yes it does. Compass, temperature, map lights, etc. all work.

I fished around under the dash looking for any obvious signs of "short-age." Found none. Pulled the glove box too looking at the lights & wires on the pass. side. Nothing there either. Pulled the radio, hvac unit, lighter.....all "looks" good. Ground strap from radio and accompanied grounds were solidly attached to grounding point.
The ash tray light was just taped on a plastic L-bracket to make the turn to the lamp....no evidence of anything there. I think I looked at everything short of un-taping the whole wiring harness under the dash (something I'm not to keen on doing.)
Possible it could be at the "infamous splice" under the hood?
Maybe I could put a 20 amp fuse in place of the 5 amp and track it by the smoke?

Based on what we are seeing in the diagram I would say most likely not related to that splice.
You may not see any "evidence" of a short, aka burns, melting, etc etc because the fuse blows before the damage could be done. One trick I have heard of that I have not personally tried (yet) is to build a fused jumper wire (or a jumper wire with a breaker on it) and use a compass along the circuit you suspect has the short. the needle will point at the wire until you reach the point of the short.
If you can find a 4a breaker that might be handy in troubleshooting/fixing this so you dont keep blowing fuses. the breaker will automatically blow and reset. you could also bypass a large portion of the circuit using a protected (fused or breaker) jumper wire.
unfortunately without being there I can't really dig into it and check it all out
I'm confident that if we keep working at it we will be able to fix it.

No I haven't. I've been really busy over the weekend with work, but hope to get back on this sometime this week.
Have you replaced your stereo recently? I just did in my 94 Ram 1500 and I keep shorting it the illumination lights I’m going to check it tonight and see if there’s something I can do to fix it
