Thank you both.
Note I said I already I checked the socket at the bulb and the connector from
the wiring harness to the bulb holder. From there the wiring merges with other
wires to become a mighty river of wiring harness, then disappears underneath
somewhere.
Tucked away on the left over near the battery and fusebox is a seemingly sealed
box, maybe 12"x10"x2", with heat-removing fins. Connected to one side are two
large multi-pin connectors, each maybe 5"x2", each with maybe 50 to 100 pins
and lots of wires. (I didn't count'em.) I was slightly afraid that removing
them might disable a theft-prevention radio or set off the alarm or something.
Nevertheless I swallowed bravely and detached and re-seated both connectors.
That made no difference. The bulb was still out. As was the jury.
So the conjection was the somewhere in the wiring harness, either under the
hood and exposed to the weather or inside the car and exposed to rain dripping
around a leaking windshield, there exists a corroded connector. Or a broken
wire. obvioulsy I can run a separate wire, but I'd rather find the real
problem. The operative question is where it might be!
Tanks again,
Jim Muller
