As an ASE-certified master technician, I’ve spent countless hours tracking down electrical gremlins in commercial vans. The 2019 Ford Transit is a workhorse, but when a circuit shorts out or an accessory stops working, finding the right fuse can save you a lot of time and money. Whether you’re a fleet manager, an owner-operator, or an adventurous van-lifer, understanding the fuse layout on your Transit is essential.
Here is your comprehensive guide to the 2019 Ford Transit fuse boxes, amp ratings, and protected circuits.
Quick Answer: Fuse Box Locations
The 2019 Ford Transit features three main fuse box locations you need to be aware of:
- Engine Compartment Fuse Box: Located under the hood on the driver’s side, near the coolant reservoir.
- Passenger Compartment Fuse Box (BCM): Located behind the lower knee panel on the driver’s side, below and to the left of the steering wheel.
- Pre-Fuse Box: Located under the driver’s seat. This box contains high-current fuses that feed the main fuse boxes and heavy-load components.
Note: Fuse layouts can vary slightly depending on your Transit’s trim level, engine (3.7L, 3.5L EcoBoost, or 3.2L Power Stroke), and upfitter options. Always verify with the printed legend on the inside of the fuse box lid.
Engine Compartment Fuse Box
This fuse box manages the heavy lifting for the engine, transmission, powertrain control module (ECM/PCM), and exterior lighting. It also houses several key relays.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F11 | 40A | Green | Anti-lock Brake System (ABS) pump |
| F12 | 40A | Green | Climate control blower motor |
| F14 | 30A | Pink | Powertrain Control Module (ECM/PCM) / Engine relay |
| F15 | 20A | Yellow | Fuel pump control module |
| F16 | 30A | Pink | Starter motor relay |
| F21 | 20A | Yellow | ABS valves |
| F31 | 15A | Blue | Headlights (Low/High beam relays) |
| F32 | 10A | Red | Airbag module (SRS) |
| F33 | 10A | Red | Ignition switch / Push-button start |
| F42 | 15A | Blue | Trailer brake controller |
| F48 | 15A | Blue | Ignition coil (Gas engines) |
| F64 | 10A | Red | A/C clutch relay |
| F65 | 30A | Pink | Trailer tow module (if equipped) |
| Relay 1 | - | Black | Starter Relay |
| Relay 2 | - | Black | ECM/PCM Power Relay |
| Relay 3 | - | Black | A/C Clutch Relay |
| Relay 4 | - | Black | Fuel Pump Relay |
Passenger Compartment Fuse Box
Located under the driver's side dashboard, this panel handles interior accessories, lighting, infotainment, and the body control module operations.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F3 | 20A | Yellow | Radio / Infotainment system (SYNC) |
| F9 | 10A | Red | Interior lighting / Map lights |
| F15 | 15A | Blue | Data link connector (OBDII) / Diagnostic port |
| F32 | 20A | Yellow | 12V Power point (Cigar lighter / Front console) |
| F33 | 20A | Yellow | 12V Power point (Rear/Cargo area) |
| F39 | 15A | Blue | Reverse camera / Parking aid |
| F42 | 15A | Blue | Power mirrors / Power windows relay |
| F44 | 10A | Red | Instrument cluster |
| F54 | 5A | Tan | PATS (Passive Anti-Theft System) transceiver |
| F59 | 20A | Yellow | Horn relay feed |
| F60 | 15A | Blue | Brake lamp switch / Tail and park lights |
| Relay 1 | - | Black | Accessory Delay Relay |
| Relay 2 | - | Black | Blower Motor Relay |
Pre-Fuse Box (Under Driver's Seat)
The pre-fuse box protects the main power distribution network of the vehicle. If you lose power to an entire fuse box or a heavy electrical load component fails completely, check here.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| PF1 | 150A | Black/Grey | Starter motor feed |
| PF2 | 250A | Black/Grey | Alternator feed |
| PF3 | 60A | Yellow | Passenger compartment fuse box (BCM) Feed 1 |
| PF4 | 60A | Yellow | Passenger compartment fuse box (BCM) Feed 2 |
| PF5 | 60A | Yellow | Engine compartment fuse box Feed 1 |
| PF6 | 40A | Green | Trailer tow module main feed |
| PF7 | 60A | Yellow | Upfitter switch interface module |
How to Test a Fuse
Before throwing parts at an electrical issue, testing the fuse is your first step. Here is the professional way to do it:
- Visual Inspection: Pull the suspected fuse using fuse pullers or needle-nose pliers. Look at the U-shaped wire inside the plastic housing. If it’s broken or charred, the fuse is blown.
- Use a Test Light: Ground your 12V test light to a bare metal surface. Turn the ignition to the "ON" position. Touch the tip of the test light to the small metal test ports on the top of the fuse. If the light illuminates on one side but not the other, the fuse is blown. If it lights up on both, the fuse is good.
- Use a Multimeter: Set your multimeter to the continuity setting (the one that beeps). Touch a probe to each test port on the top of the fuse. A continuous beep means the fuse is intact. No beep means it’s time for a replacement.
Always replace a blown fuse with one of the exact same amperage and color. Using a higher-rated fuse can melt wires and cause electrical fires.
Common Blown Fuses on this Vehicle
As a technician, I see a few recurring electrical issues on the 2019 Ford Transit. If you're experiencing problems, check these first:
- 12V Power Points / Cigar Lighter (F32 & F33 in Passenger Panel): Delivery drivers and contractors constantly plug in phones, laptops, and GPS units. A damaged charger will instantly pop these 20A fuses.
- Blower Motor (F12 in Engine Panel): If your A/C or heat stops blowing air, check this 40A fuse. Also, inspect the blower motor resistor, as a failing resistor often causes the fuse to draw too much current and pop.
- Trailer Tow Module (F65 in Engine Panel): If you tow heavy equipment or trailers with poorly maintained wiring, a short in the trailer will blow this fuse to protect the Transit's electrical system.
- Radio/SYNC System (F3 in Passenger Panel): Sometimes the SYNC screen freezes or goes black. Pulling this 20A fuse for a minute and reinstalling it performs a hard reset, which often fixes the issue. If the fuse is physically blown, look for pinched wires behind the head unit.
Electrical problems can be frustrating, especially when they disrupt your workday. If you've checked the fuses and the problem persists, it’s time to call in a professional.

Before you pull a fuse on the 2019 Ford Transit
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
