Grounds

Before checking the ground circuit from the faulty component all the way to the ground stud, check the circuit from the splice pack to ground by testing some of the other subsystems grounded by the same splice pack. If the other subsystems function properly, the path from the splice pack-to ground is good.

Ground: Circuit 150
Location: Horn connector cavity A to underhood fuse block cavity E7; then from underhood fuse block cavity E6 to left forward lamp ground.

IMPORTANT: Due to manufacturing process the cavity shown on the schematics may not match the harness.

If the following circuits are operating normally, the ground is most likely good.
- Left Side Marker Lamp
- Left Park/Turn Lamp
- Left Fog Lamp

Check for OPENS/SHORTS. Repair as needed.
