[V8] the dreaded blue wire debacle

[Ingo Rautenberg]

Steve,

Yes you did :-)  The alternator comes complete with new voltage
regulator/brush pack.  Have you checked climate control head voltage when
this occurs?  The fact that you have occasionally three IC lights dimly-lit
at the same time has me thinking a bad solder joint or other connection in
the instrument cluster, but I can't say for sure.

Bad solder joints can do aggravating things.  See:
