    Fuse or a switch

    After I put in my tripminder today and rewired my stereo, I noticed that I didn't have any instrument cluster lights, parking lights, or rear tailights. My headlights work though along with every other light inside the car (all the courtesy lights, dash lights).

    I checked the grounds and they are all fine. No wires are exposed or not covered and both my cd player and the trip minder work fine.

    Is this the headlight switch or a circuit breaker/fuse? Chances are it seems like its a fuse since I got water on the fusible links next to the coolant reservior. The headlight switch still works fine and I didn't remove it to install the tripminder. I don't have my car's owner manual so I can't figure out which fuse or circuit breaker it is.

      i think the headlight switch has built-in non-replaceable fuse links on it too. when they pop you have to replace the switch.

        It keeps blowing fuse 4 in the fuse box as soon as I connnect the battery cable, and I don't know why.

        I replaced the headlight switch and there wasn't anything wrong with the original one.

          wire up your own switches like i did, one toggle to relay for lights, one for parking lights, one for high beams, works great

            start checking ALL of your light bulbs. they can fall apart before the burn out. look at the contacts on the bottom and see it they are melted out.

              I fixed it, there was a bad ground to the tripminder. Somehow the grounds for the tripminder are tied into the same circuit as the lights.
