In this article, you will find information about the fuses of the Buick Riviera (model 1999), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Buick Riviera
The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of damage caused by electrical problems.
Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating.
Caution!
- Data on the replacement fuse must match the data on the defective fuse.
- Before replacing a fuse, turn every vehicle electrical switch off.
Location of Fuse Boxes
Instrument Panel Fuse Block:
There is a fuse panel located at the end of the instrument panel near the driver’s door.
Rear Underseat Fuse Blocks:
Two other fuse panels located under the rear seat.
To Remove the Rear Seat Cushion:
- Pull up on the front of the cushion to release the front hooks.
- Pull the cushion up and out toward the front of the vehicle.
To help avoid damage to the battery and wires, be careful when removing or reinstalling the seat cushion. Do not remove covers from covered parts. Do not store anything under the seat, as objects could touch exposed wires and cause a short.
