Hey, all, I was working on my girlfriend's 1991 Accord and the
cigarette lighter wasn't working. I tried the fuses but none were
labeled as cig lighter in any fashion, under the hood or under the
dash. I did a search on the groups but got nowhere, as did my attempts
to search Autozone's information on repair. I took part of the dash
apart (mostly, really, the center console) and removed the cigarette
lighter housing (breaking the ring in the proces (the lighter body
unscrews from a cylinder behind the plastic so try that first)) and
still had no power at the supply to the lighter (at any position of the
key).

All other electrical circuits, of course (I checked them) were
functioning properly, I checked every fuse I could find, but the
lighter had no power. I checked the ground and it was good, I checked
the connections and they seemed good.

I was about to trace the wire back to the panel when I looked more
closely at the connector that goes to the back of the lighter and saw
that it was more than a simple crimp connection to a slip connection to
fit the rod at the back of the lighter. The plastic housing hinges and
I opened it up to find that the supply wire has a crimp connection that
holds a small leaf of metal that then goes down, backwards, at an angle
to the actual slip connection that fits the back of the lighter. Where
the leaf of metal hits the slip connection there is a junction (of
course, they are two separate pieces of metal) and the connection is
made by a solder joint. That solder joint had failed.

I'm not sure why Honda did it that way, but the joint must have gotten
hot one time in the past and it melted the solder, breaking the
connection. I soldered it back and it works great. She doesn't smoke
(neither do I) so I never expect it to get hot again, problem solved.

I thought I'd post this since 1) it was a tricky problem to find and 2)
it would normally seem like a fuse problem and since it was not it
might save someone a lot of time fighting with fuses.

HTH.
