Which fuse is for the AC on a Ford F-150?
The AC system in most Ford F-150s is protected by a dedicated 30-amp fuse labeled “A/C” or “A/C Clutch” in the engine compartment fuse box. A relay may also control the compressor, and some model years include additional climate-control fuses inside the cabin. Always check your vehicle’s fuse diagram for your exact year and trim.
AC systems are driven by electrical circuits that engage the compressor clutch through a fuse and often a relay. While the engine-compartment fuse box is the primary source for the A/C clutch protection, some F-150 generations also route related power through interior fuse panels for components like the climate control module or blower motor. This article outlines where to look, what labels and amperages you may encounter, and how to proceed if the AC isn’t working properly.
Where to look for the AC fuse
Find the primary AC protection in the engine compartment’s fuse/relay box. The cover usually includes a diagram with the label for the A/C clutch or A/C circuit and the corresponding amperage. If your truck has a second fuse panel inside the cabin, inspect it for fuses related to climate control or the blower motor.
- Under-hood fuse box: A/C Clutch fuse, typically 30A. The A/C Clutch Relay may also reside in this box.
- Interior fuse box (driver-side dash or kick panel): Fuses related to the climate control module, A/C, or blower motor; amperages vary (commonly 10–20A or 20–30A depending on year/trim).
Exact designations and amperages can vary by year and trim. Always refer to the fuse diagram on the fuse box cover or the owner’s manual for your specific truck.
Common fuse ratings and labels
While the exact labels and ratings can differ by model year, these are typical patterns you may encounter when inspecting fuses related to the A/C system in a Ford F-150.
- A/C Clutch fuse: commonly labeled “A/C” or “A/C Clutch” in the under-hood fuse box; most often 30A.
- A/C Related relays: often located in the same engine compartment fuse box as the A/C Clutch fuse; may be labeled as “A/C Relay” or something similar.
- Interior climate/blower fuses: may be labeled “Blower,” “Climate,” or “A/C” in the cabin fuse box; typical ratings range from 10A to 20A, depending on generation.
Note: Always confirm the exact fuse designation and amperage for your specific year and trim by consulting the diagram on the fuse panel cover or the owner’s manual. Variations exist between generations (older body styles versus modern EcoBoost models).
What to do if the AC stops working
Begin with basic checks: visually inspect the A/C fuse for a blown condition, and test the A/C clutch relay if equipped. If the fuse is intact and the clutch relay appears fine but the AC still won’t engage, suspect issues such as a faulty compressor, low refrigerant charge, or a problem in the climate-control circuitry. When in doubt, have a qualified technician diagnose the system to avoid further damage.
Model-year variations
Ford’s F-150 electrical layout has evolved across generations (1997–2003, 2004–2014, 2015–present). The A/C fuse and its location can shift between engine-compartment and interior panels, and some years use different amperages or additional fuses. Always use the year-specific fuse diagram for accuracy.
What to bring with you
When troubleshooting, note your F-150’s year, trim, and engine (e.g., V6, EcoBoost). This information helps locate the exact fuse diagram and prevents misidentification of circuits. If you need replacement fuses, carry a variety of common ratings (10A, 15A, 20A, 30A) to confirm the correct one.
Summary
For most Ford F-150s, the primary AC protection is a 30-amp fuse labeled “A/C” or “A/C Clutch” in the engine compartment fuse box, often accompanied by a relay. Some generations include additional climate-control or blower fuses inside the cabin. Always verify the exact fuse designation and amperage using the diagram on your vehicle’s fuse box cover or the owner’s manual, and consider professional help if basic checks don’t restore cooling.
Which fuse is responsible for AC?
Typically, AC systems use “TR”-type fuses to ensure safe system operation.
Which fuse is for the AC on a Ford F150?
Right here responsible for power to AC compressor clutch. If this fuse is good then you want to check the AC clutch relay which is relay number 23. And is located.
How to reset AC on Ford F150?
To reset the A/C on a Ford F-150, try the button combination of pressing and releasing the A/C and Recirc buttons simultaneously, then pressing A/C again within two seconds. A more complete reset is to disconnect the negative battery terminal for at least 15 minutes to force a system reboot.
Method 1: Button reset
- Turn the ignition off.
- Press and release the A/C and Recirc buttons at the same time.
- Within two seconds, press the A/C button again.

Method 2: Battery reset
- Turn the ignition off.
- Disconnect the negative (-) battery terminal.
- Wait for at least 15 minutes to allow the system to completely reset.
- Reconnect the negative battery terminal and start the vehicle.
If problems persist
- Check the HVAC fuses for the A/C clutch, control module, and switch.
- If the issue is a blend door actuator, a diagnostic scan tool may be needed to perform a recalibration after replacement.
- Check for any potential software updates or recalls related to the climate control system.
Why is my Ford f150 AC not blowing cold?
F150 AC often suffers from clogged orifice tubes and low refrigerant causing insufficient cooling. If your AC blows cool but not cold, check for clogs in the orifice tube or accumulator. A blockage restricts refrigerant flow, causing uneven cooling and reduced efficiency.
