In this article, you will find information about the fuses of the Cadillac Escalade (GMT400; model 2000), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Cadillac Escalade
The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links in the wiring itself. Circuit breakers in the fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes. This protects the circuit until the current load returns to normal or the problem is fixed. 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.
Caution!
Be sure you replace a bad fuse with a new one of the identical size and rating.
Location of Fuse Boxes
Instrument Panel Fuse Block:
The fuse block access door is on the driver’s side edge of the instrument panel. Pull off the cover to access the fuse block.
Underhood Fuse/Relay Center:
The underhood fuse/relay center is located in the rear of the engine compartment near the brake fluid reservoir. Move the retainer clips for the cover to access the fuse block.
The headlamp wiring is protected by a circuit breaker in the lamp switch. An electrical overload will cause the lamps to flicker on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away.
The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow or ice, the wiper will stop until the motor cools. If the overload is caused by some electrical problem and not snow, etc., be sure to get it fixed.
