wiring/lighting help!

tak2099 · 05-14-2010, 02:46 AM

I have been having some problems with my tail lights, dash lights, and front and side marker lights. But my headlights, fog lights, turn signals and hazards still work. So I consulted the wiring diagram, and this does make sense, since they are all connected. I checked the voltage coming out of the fuse when the switch is on and i get 12 volts. So I am losing connection some where before it breaks off into the different areas of the car, most likely near the fuse. Hopefully some one knows of a connector or some kind of fusible link under the dash. Please help.(not being able to drive the beast at night is disappointing)

If you've lost the front side markers the issue's in the fuse box. The front side markers and the climate control lighting break away before the harness leaves the box for the other items.

Look it up online and see the wiring diagrams for what you need to check.
