Circuit I/P Splice Pack


Before checking the ground circuit from the switch 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, it is most likely that the path from the splice pack to ground is good (or at least one of the paths is good with redundantly ground splice packs).

LOCATION:
Taped to the harness behind the I/P cluster

FUNCTION:

If one of the following systems is operating normally, the ground circuit is most likely good.

^ Radio
^ Chime module
^ Hazard flasher
^ Window relay
^ Cigar lighter and bulb
^ I/P cluster
^ Rear defog switch

REPAIRS:
Check for OPENS/SHORTS.
