Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
I/P BATT Fuse
I/P BATT fuse is a 30A Maxifuse located in the underhood junction block. Circuit 402 is powered by I/P BATT fuse. If the headlamp switch, dome lamp, remote mirror switch, map lights (SL/SC only), power door locks, or the radio operate normally, the fuse is most likely good. If the fuse is blown, determine the cause of the blown fuse and repair. Replace fuse as needed.
