just did some long overdueroutine maintenence (spark plugs, pcv, throttle body cleaning, radiator flush). upon reconnecting the positive lead onto the battery cable and firing her up, i noticed i now have no horn, my headlights and taillights are always on whileignition engaged(even with switch in off position) and my themometer on my overhead console will not give me a reading (all other info displayed). i have no blown fuses in the fuse box under the hood.............. any ideas what it could be??? thanks for responding.
