doubt anybody can help me without actually looking at my car but i figured i'd post the issue anyway.

my tail-light/interior guage lights/license plate lights are all on the same 10amp fuse which keeps blowing. (pretty good idea to put the guage lights on the same fuse as the taillights cuz theres no way you cant know your taillights have gone out) i removed my entire tailight from the trunk and took off the bulb housing/wiring from it and managed to drain about 15oz of water from inside the taillight. i figured this had to be the problem, water was in there and splashing around and when the bulbs/bulb housing got splashed it caused a short. once drained i reassembled after letting the bulb housing/wiring dry and was good for a day or two (before i couldn't even drive a block before they would blow). i drove 250 miles on the highway and was totally cool. got off the highway and about 3 blocks off the highway BAM the fuse blew again. i got to my destination and replaced the fuse however did NOT turn on my taillights because i was not out driving at night. when i left to head home and got back on the highway for another 250 mile drive about 100 some odd miles into the drive it got dark and i had to put my taillights back on. i was TOTALLY cool until, yep, you guessed it, i got off the highway and stopped at a red light. now i'm thinking it has something to do with the brake light cuz i almost NEVER if EVER hit my brakes on the highway (i live in a very rural part of the country and theres not many people on the roads around here aka no traffic) which is why i think its not blowing when i'm driving on the highway, for no matter how long. so anyway, i'm thinking of just removing the brake light bulb? temporarily. just to see if i have the problem anymore. but i'm also thinking that becuase of the H20 in the housing the bulb housing has gotten so corroded its connecting the two contact points and causing a short. in that case i'd have to remove the entire wiring setup for that taillight and test it out. if it works without any problems then i need a new wiring setup for that taillight. or i can try and clean it with a file or something but am reluctant.

either way. thought i'd throw this out there in case anyone has ever seen anything like it before. my car is a 1990 civic dx sedan and is in MINT condition. no rust anywhere, california car, 120K miles. the rubber stripping that lines the lip of the trunk is torn in places which is how i think its retaining water in that taillight. i checked the other taillight and its BONE DRY.

thanks.
