Hello All,
1967 Eldorado
I am prepping to chase down the reason the above lights no longer work.
Does anyone have experience with this gremlin?
Where should I start to look?
Also, has anyone removed the lens on the door lamps, same car? These lights are also out.
Best,
Kelly
The fuse will be marked as 'Courtesy' on the fuse block. Just use a 12V test light on both sides of the fuses to determine which ones are blown.
Hello Big Fins,
Thank you for the response.
I will be at the car this weekend-I found this fuse box pic on the internet.
I think it's "Acc" instead of "Courtesy". I would like to be sure if possible.
Can you take a look at the pic and let me know which fuse controls the cabin lights?
Thank you!
I have checked the chassis circuit diagram in the shop manual for '67. You are right. Trunk, courtesy (and several others) are the same fuse. But it is not Accessory (Acc). It is the Body Feed fuse. In your picture it is the second fuse from the bottom left (right under Acc). It is a 25 amp fuse. Replacing it should fix the problem. Or the fuse melts as soon as one of the lights go on. Then ofcourse you havef a short somewhere (and a little project). :). Good luck!
Those can be different to troubleshoot than other electrical items because the switches are often on the ground side so keep that in mind if its not just a simple blown fuse. I don't know that the glove box and trunk are that way but the interior lights would be since there are multiple ways to turn them on. Until they came up with electronic body control modules running constant power to the lights(s) and switching the grounds was the easiest way to do it.
Progress can be reported!
The MISSING fuse for the "body feed" circuit warranted further investigation.
Upon replacing the fuse (and with a new battery) the cabin lights turned on (and stayed on with the doors closed!). The door jamb switches were removed and washed with WD-40. The underdash lights turned off with the plunger pressed, while the backseat lights stubbornly remained on. I then looked at the switch on the back seat armrest and formed a testable hypothesis-move the switch. Eureka! The backseat lights turned off. Finally, I added layers of sticky patches across from the door jamb plunger until the lights shut off when the doors closed.

Fantastic interior! is it darien cloth and leather?
The interior is "Covert", a style I thought was very much "Cold War". It's actually French.
The car was in fact a service vehicle, plying the gravel roads in central Montana. Still there is a considerable amount of Montana inside the car. I do look forward to driving the car more than tinkering.

I think that 67 Elodrdos is one of the best looking cars ever. And that interior is fantastic!
Following a short trip to the car wash, a rather distressing fluid drip followed me home! Following a certain amount of weeping and the gnashing of teeth, I then sprayed degreaser on the bottom of the engine, placed clean cardboard underneath, and prepared for the worst as I feared the leak was from the engine. The drip was traced to the POWER STEERING PUMP. An underfilled reservoir supported this hypothesis. (Another) trip to the store secured power steering fluid (with stop leak already added). The fluid is topped off with the final level to be determined after a thorough warmup.
That PS fluid leak can come from several places (albeit not as many places as transmission fluid). Did you check to see where it is coming from? It could be the pump, the hoses (and/or the connections of the hoses at the pump) or the steering box. I am not a big fan of putting 'stop leak' into these systems. it could be something simple as an o-ring that has given up.
Yes, a couple of sources of power steering hose leaks. The 50-year-old hoses have given up the ghost. I have an appointment with a mechanic to address the issue. This means another return to Montana to take her for a spin!
