This has gotten a bit interesting. I decided to methodically make sure all bulbs, connections, etc. for all lights were working well. I found 4 bulbs that needed attention and were replaced; a passenger front fog light, brake light in rear panel door (reminder this is a wagon), the driver front side marker light, and one of the rear license plate lights. These were all fixed. Now two license plate lights, three reverse lights in rear panel, one brake light in rear panel, two brake lights in rear lens, two tail lights in rear lens, two marker lights in rear lens, two high beam headlights, two low beam headlights, two front fog lights, and two front side marker lights work when powered. However, I still get independent “lamp defective” messages when I press on the brakes or turn on the fog lights. The fog lights do not illuminate when the fog switch is turned on, there is no voltage to the bulb connector. However, the fog lights do illuminate for the approximately 10 seconds when the door is closed after the lights have been switched on. Any suggestions/comments appreciated. Sorry for the length of these comments but wanted to have all the information presented.
