Default 98 dash lights gone crazy

Started with both blinker light indicators flashing when blinker used (as if caution lights were on).
When car was then turned off the entire dashboard including radio and climate buttons began flashing like crazy.
Front blinker light bulbs were replaced because they were not lighting. Issue continues.
1998 C 5 with 180,000 miles
Suggestions please
Thank you

You might try repeatedly pressing and releasing the hazard light switch.

All those circuits run through the Multifunction Switch, particularly the dash lights.

Turn signal lever, headlight switch, multifunction switch, are some of its names. I believe it has 19 circuits going through it.
