GMC Terrain: Electrical System / Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems.
Danger
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. Use of an oversized fuse or circuit breaker can result in a vehicle fire. You and others could be seriously injured or killed.
To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.
Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as possible.
There is a fuse puller in the engine compartment fuse block. See Engine Compartment Fuse Block. It can be used to easily remove fuses from the fuse block.
To identify and check fuses, circuit breakers, and relays see Engine Compartment Fuse Block or Instrument Panel Fuse Block and Rear Compartment Fuse Block.
Electrical System Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the electrical load current is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed...
Engine Compartment Fuse Block
To remove the fuse block cover,
squeeze the clips on the cover and
lift it straight up. See Engine
Compartment Overview.
Caution
Spilling liquid on any electrical
component on the vehicle may
damage it...
