Alright so i have a 1982 rabbit convertible when i first purchased it only a few lights would turn on, so i cleaned all the plugs in the fusebox and the ends that connect to the blubs and got most of them working. but the next week they were not working again, i tried to clean them up, no good so it sat for a couple months, now im up to trying to get the lights to work again, so i go to check, nope still only one headlight and the rear emergency flasher that work. i go to check the plug on the fusebox and it has tons of corroded pins and plugs, and i look closer and one of the pins has come clean off, so deciding that will never do, i buy a brand new fusebox, (it isn't even a day old yet) install it, nope still the same ol' problem, really i don't do much work on cars, nonetheless volkswagens or anything electrical,
so to get to my point i was wondering if there is a list of things i can troubleshoot, its a neat lil' car and i would like to enjoy it, but it's lights just won't work
please send help
