Just thought I'd feedback what I learned recently when working on my rear compartment cigar lighters. Not a big deal, I know, but if it helps anyone else out then it will have been worth posting.
Okay, so I don't smoke and most people I know don't either...and even if a smoker was riding with me in my 64 Fleetwood I'd never allow them to light up a cigarette or cigar. So, yes, it may sound daft that the rear compartment lighters not working had been bugging me, but if something is there then I just don't feel right knowing it's not working!
Basic checks confirmed that (a) both lighter bases had a live feed going to them and (b) that the lighter elements worked fine in the front bases. After a little more investigation, prompted by Jason alerting me to the fact that these rear compartment lighter have fuses that screw into the bases, I determined that the fuses were indeed no good. My next step was going to be to make some kind of modification to the bases in order to bypass these fuses, but just before I set out on that I thought I had nothing to lose so pried open one of the fuses to take a look.....just a few metal tabs that need bending back and they open up easily.
Inside is a metal spring that is supposed to bridge the gap between each end of the fuse holder and acts as the fuse itself. I found that this seemed to have compressed over time and was not quite making contact at both ends. It was also quite badly oxidised. I cleaned it up and gently stretched it so that it would act as a spring again, which meant that I had to hold the two fuse sections together as I was pushing the metal tabs back down to secure it all back together. Then I tested it and found it to be working fine. The second fuse needed the same doing but I also had to clean up another pair of contacts in the base section.
