99 Z24 Data link and head light problem
Tuesday, February 02, 2010 11:14 PM
Hey all I just bought my first Cav its a 99 Z24 5 speed. I got home and noticed that none of the headlights work or the front turn. The rear lights work, the reat turn is dim when i use the switch but if i turn on the hazerds they blink fine (just the rear, still no fronts). The check engine light is on too, but when i plug in my scanner it turns on but then tells me to pulg in to the DL, so its not reading anything. Does any one have some input.

Try checking the fuse for the cig lighter. It is on the same circuit as the DLC. As far as the lights, I would try checking grounds and make sure all the harness plugs are connected.

OK so this is what i got so far...... I found that the car was hit in the front and there is a bunch of plugs that r not connected but they dont look like they r for the lights, they r on the right side under the car. Ok When I turn on the head lights the dont come on and the left turn light in the cluster comes on and stays on . I checked the cig plug it has power and the fuse is still good but DLC has no power. the car runs great. And not sure were the ground is for the lights? thanks for the help guys, I really like the car and hope i can get this all fixed.

if you havent found out why the headlights dont turn on, try replacing the light switch thingy,. (to turn the headlights on) i had to do that in my blazer because the DRL's came on but no headlights, replaced the lightswitch, and the headlights came on
