Over the few years I've owned and refurbished this 82T, there have been a series of electric wire gremlins I've had to deal with, fixing them one at a time whenever I had the time. Loose, corroded or broken connections, ground issues, or component failure were the usual suspects. But one issue has bugged me for way too long, until I resolved it today. For three years the opened driver side door wouldn't turn on the interior lights like the other three doors. The opened driver side door would cause the key warning buzzer to go off, but not the light. The door switch and wiring was sound, but beyond that I didn't trace the problem, fearing I'd have to remove the car interior and physically trace the wire. But just last week I used the Haynes manual wiring schematic to trace down and correct a temp sensor issue, and that gave me the confidence to seek it's help with this issue. The problem with that Haynes schematic is that it's not entirely correct, or thorough enough. What I learned (with the help of a magnifying lens to see the details on the schematic) was that all the door switches that control the interior lights runs through the key warning (buzzer) relay under the rear seat. With that relay removed and the help of a multi-meter to check for continuity, I was able to determine how the grounding circuit worked. I also learned that the wire which runs from the driver's side front door switch to the relay was sound. The problem was the relay itself. So until I obtain a relay replacement, what I did was simply jumper the driver's front door wiring to the relay connection which operated the other three doors. Why the driver's door switch had it's own seperate relay connection I don't know. All I know is that it now works.
