At the risk of boring you all, I think I have a resolution – there was no problem with the door jam switches. I am 95% certain the problem is a short in the courtesy light circuit which is linked with (1) keyless entry module, (2) retain accessory power module and (3) an alarm system I had installed the first month I bought the car (May 1995). The keyless entry and alarm appear to be located below the glove box
The welding work I had done required moving the passenger kick panel which must have disturbed the aftermarket alarm system ‘spaghetti’. While I have not “found” the short, my shifting the spaghetti seems to have alleviated the problem. My next steps are unclear as this problem has not occurred for more than 22 years. Unless it resurfaces, I am inclined to leave well enough alone.
Thanks to those who tried to help
