2008 Cadillac Escalade Esv Ignition Electrical Diagram
Fuse box diagram (fuse layout), location and assignment of fuses and relays Cadillac Escalade, Escalade ESV/EXT / 6.2L and 6.0L Hybrid (GMT900; 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014).
Checking and Replacing Fuses
The wiring circuits in the vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links. 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.
Note
- Before replacing a fuse check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
- Do not repair fuses and never replace a blown fuse with one that has a higher amp rating. This can cause damage to the electrical system and fire.
- Never replace a broken fuse with anything other than a new fuse. Use always an intact fuse of the same color.
- If a fuse blows again contact authorized services.
- You can remove fuses with a fuse extractor. To remove fuses if you don't have a fuse extractor, hold the end of the fuse between your thumb and index finger and pull straight out.
- Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
