    While I was driving home tonight, I noticed that my AC panel was not lit up, then I also noticed that my parking lights were not working as well. When I finally got home I discovered that my tail lights did not work when I had my head lights on but worked when I pushed the brake. I got under the panel and checked the fuses and low and behold the 10AMP fuse for the tail light was burnt out. I got a spare fuse and put a new one in and when I turned my parking lights on it blew the fuse once again. I haven't done anything new to my truck in a few weeks so I am kind of clueless to what could be causing my truck to keep blowing fuses. I would go out and get more but I don't want to risk getting pulled over. Any input would be much appreciated.

    What are the last few electrical related items you've done to the truck?? Whatever they are-Go back and check all the grounding points. Get some dry towels and some sandpaper and alcohol- Clean all of them and make sure they are solid contacts.

    My buddies WRX has a full engine grounding harness that had to be cleaned and re-installed after we dropped his hew HID headlights into the car. It's hinky that it jsut started outta no where without a related mod- but it's a great place to start.

    The last thing I did was install my XM satellite radio and that was over a month ago. I'm about to go grab some more fuses and start trouble shooting. I think it might have to do with my fog lights being tapped into my parking lights, possibly causing a short somewhere.

    She's gone but not forgotten.
    Last time that happened to me it was in my Corolla. Nearly identical symptoms. A real fun time to find it.

    It was the wiring at the trailer hitch. Rubbed through in one spot, only grounded out when I made a right hand turn.

    That's what I thought too. But I disconnected my fogs and tested it again and I blew the fuse once again. I downloaded the Taillight circuit just to see what all is in that circuit. The problem is my aftermarket alarm is also tied up in there somewhere. I didn't do it myself so I have no clue how it is hooked up. I noticed about a couple of weeks ago, when I armed and disarmed my alarm my parking and tail lights didn't flash anymore, yet to my knowledge my parking lights and tail light still worked fine at the time. I attached the diagram.
