[V8] Ron - find anything on the "box"

[urq]

... when you said that you replaced the dimmer does that mean that you
replaced the PC board with the potentiometer that controls the illumination?
If you replaced the potentiometer with a known good unit then obviously
you'll need to look elsewhere.  I've got similar problems on #344, but I
know it’s the potentiometer.  It does not have a stop at either end of
travel, as if some PO forced it past the end.  

There's some chance that disassembling the IC and applying the contact
enhancer of your choice to the pins would help ... 

Check the wiring diagram ... I'm pretty sure the lights in the IC proper are
controlled by the dimmer potentiometer directly, not the external buffer, if
that is the case and you see the lights in the IC misbehaving it would
exonerate the external buffer.

Sorry, guys - didn't mean to confuse anyone.  The orginal question was this
- My dash lights are intermittant, what is the problem?  Usually they will
come on when you first turn the lights on, after a while they will go out.
A good whack on the dash will usually bring them back on.  Sometimes they
will only "glow" - almost like you have turned them down with the dimmer.  I
have tested the switch on the collum - tested ok, I have also replaced the
dimmer in the IC with a known good one.  I have not replaced the whole IC as
of yet but I do have one to test with, but it has other issues!  I was
thinking that it could be the black control box under the center vents in
the consol, but as Ron mentioned he doesn't think that is the problem.
Anybody else want to chime in, go ahead.  Or if you think it is in the IC -
then where exactly can I look?  Thanks.
