My left side taillights were out, brake and turn signals work fine but running lights were out. So I checked the bulbs, they were fine so I checked the fuse, blown. replaced with a new fuse and it blew as soon as I turned my lights on. So I took all my left side bulbs and harnesses out to see out it was a harness then tried it again, still blew. Where should I look? I'm guessing it's a bad wire somewhere? Any help would be appreciated. 1995 Cadillac sedan deville base. Oh and the third light that is in the center up top also doesn't work. Thanks
