In late production 1992, the fuse size on two circuits was increased in response to comments of nuisance fuse blows. If the radio fuse or the passive restraint fuse is blown and a wiring or component malfunction is not detected, refer to the following procedures to determine if fuse size can be increased.
PROCEDURE: Radio Fuse
The 5 amp "RADIO" fuse (fuse #10), located in the instrument panel junction block (IPJB) can be increased to 7.5 amp on all 1991 vehicles and 1992 vehicles built before, and including VIN NZ181696. Vehicles built after, and including VIN NZ181697 have already been equipped with the 7.5 amp fuse.
Passive Restraint Fuse
The 20 amp passive restraint ("PREST") fuse (fuse #16), located in the instrument panel junction block (IPJB) requires a wiring change to accommodate the increased current capacity if the fuse size is increased.
Some 1992 vehicles, between VIN NZ156919 and NZ181696 are equipped with revised wiring. Vehicles built after, and including VIN NZ181697 have been equipped with the 25 amp fuse. To determine if the vehicle is equipped with the revised wiring:
o Remove the front ashtray from the center console.
o Observe the part number tag on the wire harness located below the ashtray opening in the console.
o If there is no part number tag present, the fuse size cannot be increased.
o Only if the part number on the tag is 21021757 through 21021766 can the passive restraint fuse size be increased to a 25 amp fuse.
If the fuse size is changed, mark the revised fuse size on the fuse location label on the inside of the passenger side, close-out panel.
