    To test my test light, i hooked it up to the dash and stuck it in the cigarette lighter. Well, it sparked and now some weird stuff is happening. When i push in the cigarette lighter the interior lights come on but are really faint and the clock gauge also stops working. When i open the door only the interior light under the dash comes on(bright, normal) but the one on the roof dont. Anyone have any idea what I coulda done?

    The center at the end of the lighter hole is positive, the outside is negative. You must have touched the two.

    Sounds like a fusable link blew, but I don't know where on your truck.

    There is a relay on GMs that control the dash, door and dome lights which was on my 91 Firebird. It was hell to find the problem and hell to find the part. I don't know how it would be tied in to the cigarette lighter, though.

    This is a stupid question, but did you check the fuses?

    check to see if you have melted any of the wires coming off the lighter. I burned one wire in a group of about twenty that gave me similar problems before almost burning my truck to the ground. Had to rewire the entire thing. Check out hot rod wires for an awesome deal on complete gm wiring systems. That's where I got mine. Incredible customer service. My dumbass must have called him 30 times and he never got upset.

    Just pull the ashtray and unplug the wire to the back of the cigaretter lighter and see if that works that will tell you if the lighter plug itself is the problem.

    does the horn work? if not i would say that the horn fuse is blown. my cell charger shorted the cig lighter circuit, and blew the horn fuse.

    cool, i picked up some fuses. (these ones are kinda neat, they light up when they blow). And now everything works like it should. I must have passed that fuse when i first checked. Thanks ryan for that last and final idea! Thanks everyone who replied to the thread. Gotta love CK5 and the answer came extremly fast!
