2002 Ford Ranger Fuse Box Diagram: Full Fuse and Relay List
Your 2002 Ford Ranger has two fuse boxes. One panel is at the left end of the instrument panel. The other, the power distribution box, is in the engine bay near the fender and firewall. The cigar lighter is fuse 17, rated 20A, in the interior panel, not the engine bay box.
Where are the fuse boxes on a 2002 Ford Ranger?
Passenger compartment fuse panel. Left end of the instrument panel, driver’s side, behind a removable access door. The door holds spare fuses and a plastic fuse puller clipped inside it.
Power distribution box. Engine compartment, driver’s side, near the front fender and firewall, close to the brake master cylinder. Ford also calls this the fuse and relay box, and its layout depends on which engine your truck carries.
Most sites get this wrong: fuse 6 changed the year before yours
The 2001 to 2003 Ford Ranger reads like one generation online, so most fuse charts republish a single table across all three years. That merge hides a real change that lands right on your model year.
I cross-checked The Ranger Station’s year-split reference table, Ricks Free Auto Repair Advice’s 2002-specific page, and Fuse-box.info’s 2002-2003 table. All three agree fuse 6 in the passenger panel goes live at 2A for the brake pressure switch starting your 2002 model year. The same three sources call that position not used on the 2001 truck.
Two other sources still carry the older answer. Fuseboxinfo.com’s own 2002-specific page marks fuse 6 not used, the same answer several sites give for 2001. StartMyCar’s 2002 owner’s-manual-sourced table leaves fuse 6 off its list entirely, consistent with treating it as unused.
That is three sources against two on a fuse that plenty of sites get wrong by copying the 2001 chart forward one year. Your box cover legend, printed inside the access door, is the final word for your specific truck.

2002 Ford Ranger power distribution box fuse chart
Engine bay, driver’s side. The layout splits by engine. The 3.0L and 4.0L V6 box is shown in full below, since it covers most 2002 Rangers on the road. Every value here matches the 2002-specific StartMyCar and Fuseboxinfo.com pages exactly, and also matches the 2001 truck’s box, so nothing changed here between those two model years.
| Fuse | Amps | Circuit protected |
|---|---|---|
| 1 | 50A | Instrument panel fuse panel feed |
| 6 | 50A | ABS pump motor |
| 7 | 30A | Powertrain Control Module (PCM) |
| 8 | 20A | Power door locks, remote entry |
| 11 | 50A | Starter relay, ignition switch |
| 12 | 20A | Power windows |
| 13 | 20A | 4×4 motor |

Relays in this box: wiper hi/lo, wiper park/run, fuel pump, trailer tow, A/C clutch, front washer pump, fog lamps, PCM, blower and starter.
2.3L four-cylinder power distribution box. Positions 1, 6, 7, 8, 11, 12, 16, 21, 23, 24, 25, 31, 33 and 41 match the V6 box. Fuse 13 does not appear. 4×4 was not paired with the 2.3L that year.
Fuse 17 is live at 20A for the auxiliary cooling fan, a position the V6 box leaves unused. Positions 28, 30, 38 and 42 do not appear on the 2.3L box at all. Those circuits route through different positions not covered by the sources checked here.
What if a fuse keeps blowing on your 2002 Ranger?
A fuse that blows once is usually a fluke. A fuse that blows again within a week means the fault is upstream, not in the fuse itself.
| Symptom | Check this fuse |
|---|---|
| Cigar lighter dead | Fuse 17, passenger panel, 20A |
| Second 12V outlet (auxiliary power socket) dead | Fuse 22, passenger panel, 20A |
| Radio or display dead | Fuse 20, 28 or 29, passenger panel |
| Wipers do not run on any speed | Fuse 16, passenger panel, 30A |
| Horn does not sound | Fuse 35, passenger panel, 15A (trucks without TCSM) |
| Gauges or instrument cluster dead | Fuse 11, passenger panel, 7.5A |
| 4×4 will not engage electronically | Fuse 5, passenger panel, 15A, and fuse 13, engine bay (V6 only), 20A |
| Brake warning light or brake pressure switch circuit dead | Fuse 6, passenger panel, 2A. Live only from your 2002 model year on, see the note above. |
| Both headlamps out | Fuse 33, passenger panel, 15A, and fuse 24, engine bay, 30A |
| One low beam out, bulb tests good | Fuse 38 (left) or 42 (right), engine bay, 10A each. V6 box; see the 2.3L note above. |
| No crank, no start | Fuse 11, engine bay, 50A |
| ABS light on, pump does not cycle | Fuse 6, engine bay, 50A. Different fuse from the passenger panel’s fuse 6. |
| No fuel pump prime, engine cranks but will not start | Fuse 23, engine bay, 20A |
| Blower motor or heater fan dead | Fuse 16, engine bay, 40A |
| Power windows dead | Fuse 12, engine bay, 20A |
| Power door locks or remote entry dead | Fuse 8, engine bay, 20A |
| A/C compressor clutch will not engage | Fuse 25, engine bay, 10A |
| Truck won’t start, security light flashing (PATS) | Fuse 19, passenger panel, 25A |
If the replacement fuse blows again immediately, stop replacing fuses. Check for a short or a chafed harness instead.
A cheap fuse assortment kit covers every rating on this truck and costs less than a single dealer visit. Any brand meeting the ATO/ATC mini fuse standard fits. Fuse assortment kits on Amazon.
Where is the cigar lighter fuse on a 2002 Ford Ranger?
Fuse 17 in the passenger compartment panel, rated 20A. It shares the position with the data link connector. So a fault code reader that won’t power up points at the same fuse.
A second, separate 12V outlet runs through fuse 22 at 20A. That is a common mix-up on trucks with both an ashtray lighter and a separate accessory socket.
Is the 2002 fuse layout the same as 2001 or 2003?
Not the same as 2001. The fuse 6 change covered above is the one confirmed difference between those two model years, and it only runs one direction: not used in 2001, live at 2A starting 2002.
The rest of the passenger panel and both power distribution box variants carry over unchanged from 2001 to 2002, per every source checked for this article. If you have a 2001 Ford Ranger instead, use that chart, not this one, since fuse 6 is the one number that does not carry across.
Closer to 2003. The Ranger Station’s year-by-year notes list only one confirmed change left inside this generation: the right and left stop/turn trailer tow connector fuses at positions 3 and 7 swap sides for the 2003 model year. That swap has not happened yet on your 2002 truck. Treat this chart as accurate for a 2003 Ranger except for that one item.
Ford redesigned the panel completely for 2004, a 35-position Smart Junction Box that shares no numbering with this one. If you have a 2004 Ford Ranger, none of the fuse numbers on this page apply to your truck.
If the fuse keeps blowing after a fresh fuse, what next?
A fuse protects the wire, not the part. A short to ground or a chafed harness blows a fresh fuse in seconds. No amount of fuse-swapping fixes that.
At that point you need to read live data rather than keep guessing, which means a scan tool. Our Ford diagnostic tool comparison covers what actually works across these trucks.
A basic multimeter set to ohms will confirm a short to ground first. Check the ground straps at the engine and frame too. A corroded ground is a common, cheap cause of a circuit that blows fuses only under load.

Assignments vary by trim, engine and options. Your box cover label is the final authority for your specific truck.
Ford renumbers these boxes at generation lines. This chart is for 2002 Rangers only.
It does not carry over to a 1998-2000 Ranger or a 2004-and-later truck. Those use different panels entirely.
