Opening drivers door, interior lights come on. Close driver door, timer turns lights off.
Open pass door, no lights. Leave pass door open, disconnect battery, reconnect battery interior lights come on. My car is 86 convert 4+3. When I do the disconnect/reconnect the button on the back edge of the door will work the tonneau cover. Close the pass door, then open it , no lights, cover release button inop.
What is happening when the battery is reconnected.
I suspect a relay, or maybe the small board that controls the interior lights.
Thanks for any help in this area.
