My '03 Baja failed inspection for a passenger side front blinker light being out. I replaced the bulb and thought all was good, took car back to have re-inspected but was told the tail lights were out. went to replace the bulbs in rear, but none appeared to be blown so checked the # 5 fuse and that was blown. I replaced that fuse and it blew immediately. checked bulbs again and also checked sockets for corrosion, all appeared fine So I tried Having the front running lights with the sockets not hooked up but back lights fully intact, and the back lights worked. If I then plug in driver side front light socket the fuse doesn't blow, however, if I add a bulb to that socket, or have passenger side socket installed at same time as driver side, the fuse will blow. My question is: Has anyone had this type of issue and how did you resolve it?
