When I came into the garage to take something out of the trunk of the 1958 Seville yesterday, I pushed the trunk release button in the glove box and... nothing happened. I pushed again and instead of hearing the trunk pop open and the sound of the pull down motor going up, there was just nothing happening. This was when I noticed that the interior lights did not come on either... The battery was completely dead.
So there was no other way than hooking up the charger. Two hours later, the battery was strong enough to start the car. I checked all electric components and everything seemed to work - so I was wondering what drained down a fully charged battery over night? This was the moment when I noticed a clicking noise coming from the passenger door. I opened all windows including the power vents . When I opened the passenger door the vent window started to close itself! So even when the vent window was fully closed, the window motor would still draw current. At a test drive with the door closed (of course)- the window would eventually start closing itself again.

So I had to remove all the window switches and unscrew the kick panels. Of course some of the cables behind there were broken or had the isolation coming of at the areas where they had to bend each time the door was opened or closed. I replaced one section of a cable and isolated the other ones.
So far everything seems to be working o.k. now. After an extensive test drive and opening the doors multiple times - everything seems to be well.
It is really a pain to get access to all these cables and trying to repair them. Some smaller hands would be very handy in this cases.

Thats the area behind one of the 1958 Eldorado kick panels where the cables have to bend all the time. After 51 years they seem to get tired.
