CHANGING A FUSE
Fuses
WARNING: Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components.

FAQs
The 2019 Lincoln MKZ Hybrid has two fuse boxes.
The main fuse box is located in the engine compartment.
The second fuse box is located in the passenger compartment and contains fuses related to various interior functions.
To access the fuse boxes, you need to open the hood for the engine compartment fuse box and locate the interior fuse box inside the car.
Fuses protect electrical circuits from overloads, preventing damage to components and potential fires.
Visually inspect the fuses or use a multimeter to check for continuity.
No, it’s important to replace a blown fuse with one of the same amperage rating to maintain proper protection.
A fuse puller or needle-nose pliers can help remove fuses, and a flashlight for better visibility.
There may be spare fuses located in the fuse box cover or within the fuse box itself.
Overloading a circuit, short circuits, or faulty electrical components can cause blown fuses.
It’s not advisable, as a blown fuse may affect critical systems, leading to potential safety hazards or damage.
The fuse box covers a diagram indicating the purpose and location of each fuse.
Turn off the ignition, disconnect the battery if necessary, and wait for a few minutes to allow the capacitors to discharge.
It’s recommended to use fuses from reputable brands with the same specifications as the original ones.
If troubleshooting and replacing fuses don’t solve the problem, it’s advisable to consult a qualified mechanic or contact the Lincoln dealership for professional assistance.
