Town Car No Tail Lights

Yeah, that’s what I was hoping it isn’t. New development now that I’ve started looking at it. I went to it today and everything was working. I ran it for 10 minutes with the headlights on and the tail lights were on. I then went to the fuse panel and rattled fuse #1, which is one of about 8 going to the LCM and the tail lights went off. I turned off the car, pulled the fuse and found that the fuse metal leads have a coat of tarnish. I replaced it with a new fuse, and tried the lights again and they’re on. So I figure this MIGHT have been the cause. Time will tell. I dread the cost of replacing the LCM if that turns out to be the problem.
