You turned off the dash light brightness control switch or blew a fuse.
If you have power at the dash illumination fuse, the dimmer switch may be faulty.
Check the 1993 Park Avenue fuses first. Check the light dimmer switch to make sure that it is functioning. If these are ok, look for a bad wiring connection.
Farther away!
That is the dash light dimmer control switch.. Rheostat = Dimmer. Bright to dim.
Fuse/ Dimmer Switch/ Illumination switch/ or just a new cluster all on its own. depends on what broke
On the gauge cluster it should be the left knob. Just turn it.
I would check the headlamp dimmer ; it is possibly fried.
How bright a star appears depends on both its actual brightness and how far away it is. The farther away a star is, the dimmer it appears. A bright but very distant star many therefore appear dimmer than a less bright star that is closer to us.
Its the dimmer switch bad.
This is usually an indication that the dimmer switch is in need of replacement.
Check the dimmer switch
the dimmer rehostat is faulty..if you drive with the dash on full bright all the time anyway you can jump out the dimmer by jumping the two end wires on the dimmer plug
A beam of light becoming dimmer is a physical change since it is reversible. Recharging its source will make the light beam bright again.
