6-68 Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of maxi
-fuses,
mini
-fuses and circuit breakers. This greatly reduces the
chance of fires 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.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.Instrument Panel Fuse Block
The instrument panel fuse
block is located on the
passenger's side of the
vehicle, under the
instrument panel and under
the toe
-board.
Remove the toe
-board and carpet covering to access the
fuse block. Then turn the fuse block door knob and pull
the door to access the fuses.

Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see ªWiper Blades,
Cleaningº in the Index.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. (See ªRecommended Fluids and Lubricantsº in
the Index.)Manual Transmission Check
Check the transmission fluid level; add if needed. See
ªManual Transmission Fluidº in the Index. Check for
leaks. A fluid loss may indicate a problem. Have the
system inspected and repaired if needed.
Automatic Transmission Inspection
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. Check for leaks. If a leak occurs, take the vehicle to
your Chevrolet dealership Service Department and have
it repaired as soon as possible.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part D.
Body Lubrication Service

and latches, including those for the hood, rear
compartment, console door and any folding seat
hardware. Part D tells you what to use. More frequent
lubrication may be required when exposed to a
corrosive environment.
