I have the exact same Problem on my 97. I think I narrowed my fault to the Keyless Entry Box. If my lights are stuck on and I tap that box the lights will go out. I also have an issue with the Tail Lights intermittently not working and I think it’s also related to that box. I haven’t had the time to source another one yet to try to fix the issue.
I also have another problem with my trailer plugs not operating and I don’t know if they also go through that box.
