It is possible that there is a problem with moisture causing a short circuit if all the dash lights come on. It could also be a faulty relay or alternator.
On my 1995 it is under the the dash where the clutch would be located. It is chrome colored and has plugin visible. I am certain the 1992 is identical.

You may have a burnt out bulb that is causing your tail lights and dash board lights to not come on in your 1992 Bonneville. It can also be a blown fuse that is causing your problem.
Tear the dash out. It may be clogged. Try applying water pressure to the hoses coming of your firewall.
The alternator may not be charging. Take it to your local auto parts store and have the charging system tested.
theres no easy way dash have to come out.
