ISSUE:
A no start condition or power accessories that do not work may be caused by a loose or disconnected wire at the ground buss connector. The
wire leads from the ground buss connectors may be looped under the carpet at the lower edge of the cowl trim panel. This type of routing
allows the occupants feet to apply enough downward pressure on the carpet to pull one or more ground terminals from the ground buss
connector. Accessories and systems that could be affected are in the 1989 Electrical Vacuum Troubleshooting Manual (EVTM), pages 16
through 19. A partial list of these accessories and systems are:
^
Power door locks
^
Power windows
^
Power seats
^
Keyless entry
^
Luggage compartment remote release
^
Interior courtesy lamps
^
Passive restraints
ACTION:
Inspect the driver's side ground buss connector (G-300) and the passenger's side ground buss connector (G-301) for loose or disconnected
ground wires. Refer to the following procedure for service details.
