The Jeep Grand Cherokee WK is a mid-size SUV that was produced from 2005 to 2010. It is equipped with two fuse boxes: one located under the hood and the other located in the passenger compartment.
The fuse box under the hood is responsible for protecting the electrical components of the engine and drivetrain. The fuse box in the passenger compartment is responsible for protecting the electrical components of the interior of the vehicle.
This article provides fuse box diagrams for both the under-hood and passenger compartment fuse boxes of the 2005-2010 Jeep Grand Cherokee WK. The diagrams show the location of each fuse and relay, as well as the amperage rating and function of each fuse and relay.
