Help! Instrument lighting Outage???

[Turse, Thomas (CORP, GEAccess)]

Hey All,

Hoping someone has a quick fix on this as the archives seem to point to very
complex solutions.  On my 1990 80Q all the dash lights were working fine- no
bulbs out and nothing done to the car electrically that could have an effect
on the lights.  Checked the instrument cluster fuse and it is fine.
Everything else seems to work and the radio, warning, and aux button lights
(fog, defroster, etc.)are all working. Is there something other than the
fuse that could cause this- no water issues or any occurrence that should
warrant this.  I just had the car in for an A/C charge and belt tightening
but not sure how or if this could have caused the problem.  Any suggestions
would be greatly appreciated as I don't really want to go to a dealer for
major diagnostics.  Please send any replies to me directly as I don't
receive posts at work.

TEA,
