Frequently Asked Questions (FAQs)
My cigarette lighter or 12V power outlet is not working. Which fuse should I check?
The 2004 Grand Cherokee usually splits the power outlets across different circuits, which are protected by fuses in the Interior Fuse Panel.
Cigar Lighter (Front): Check Fuse #26 (15 Amp Lt. Blue), labeled “Cigar.”
Power Outlets (Dash/Rear): Check Fuse #9 (20 Amp Yellow), labeled “Power Outlets.”
Rear Power Outlet: Check a separate 20A fuse/relay in the PDC (Underhood), often labeled “Rear Pwr Outlet.”
The radio or amplifier suddenly stopped working. Which fuse is for the audio system?
Check the Interior Fuse Panel.
Radio/Amplifier: Check Fuse #5 (25 Amp Natural), labeled “Radio/Amplifier.”
Radio (BCM controlled): Check Fuse #30 (15 Amp Lt. Blue), labeled “Radio” (often controls the head unit’s main power).
One or more power windows stopped working. Is there a fuse for the windows?
Window issues are commonly caused by a bad regulator or motor, but you should check the circuit breakers first.
Windows: Power windows are protected by a 20 Amp Circuit Breaker (C1) in the Interior Fuse Panel, labeled “Wiper.”
Main Power: Also check Fuse #12 (50 Amp), labeled “Power Windows,” located in the PDC (Underhood).
My A/C blower motor only works on high, or has stopped completely. Where is the fuse?
Blower motor failure is often a bad resistor or a melted connector, but the main power is protected by a fuse in the PDC (Underhood).
Blower Motor: Check the large Fuse #1 (40 Amp), labeled “Blower Motor,” in the PDC (Underhood).
Heater Relay: Also check Fuse #23 (15 Amp), labeled “Cabin Heater Relay,” in the PDC (Underhood).
I have no airflow control (air only blows out the defrost vents). Could a fuse fix the blend door actuator?
The “blend door” or “recirculation door” is controlled by an electric actuator. While the actuator itself is a common failure point, a blown fuse could cut its power.
Fuse: Check the fuses related to the HVAC/Body Control Module (BCM) in the Interior Fuse Panel (e.g., Fuse #28, 10 Amp Red). A power loss to the BCM can cause the actuators to fail their self-test.
My Jeep cranks but won’t start. Which fuse controls the fuel pump?
The fuel pump circuit is located in the PDC (Underhood).
Fuel Pump: Check Fuse #24 (20 Amp), labeled “Fuel Pump.”
ASD Relay: Check the Auto Shut Down (ASD) Fuse #6 (30 Amp) in the PDC, as the ASD relay provides power to the fuel pump, ignition coils, and fuel injectors. If this fuse blows, the engine cannot run.
