2017 Jeep Wrangler — Fuse Box Diagram & Amperage (JK)

Quick answer

• Under-hood: Power Distribution Center (PDC), also called the TIPM, on the right (passenger) side of the engine bay next to the battery. This houses virtually all fuses and relays on the 2017 Wrangler JK.
• Instrument panel/dash kick-panel: Not equipped on the 2017 Wrangler JK (no separate interior fuse box).
• Trunk/cargo: Not equipped (no separate rear fuse box). Tow-package modules live near the left rear quarter, but their fusing is still in the under-hood TIPM.

Always confirm fuse cavity numbers and ratings against the printed legend inside your TIPM cover; Jeep varied assignments by trim, options (tow package, heated seats, etc.), and market.

Under-hood Power Distribution Center (PDC/TIPM)

Location: Right side of engine compartment beside the battery. Squeeze the two cover tabs to remove the lid; the underside of the lid has the definitive cavity map and fuse/relay legend for your specific Jeep.

Below is the most common 2017 Wrangler JK layout by circuit. “Fuse #” refers to the cavity ID molded in the TIPM (often shown as M- for mini fuses and J- for larger cartridge/J-case fuses). Where Jeep frequently varied the cavity, we note “Varies (see lid).”

Relays in this TIPM: The 2017 JK uses a mix of plug-in and solid-state (internal) relays inside the TIPM. Common functions include Starter, A/C clutch, Horn, Radiator fan, and Fuel pump. The exact relay cavities are printed on the TIPM lid (often labeled “R” followed by a number). Note that several relays (including the fuel pump and fan control) may be non-serviceable solid-state drivers within the TIPM.

Important: Fuse cavity numbers and some ratings differ with options (manual vs. automatic, tow package, lighting packages, etc.). Use the TIPM cover legend as the final word.

Instrument panel / dash fuse box

Not equipped on 2017 Wrangler JK. All serviceable fuses are in the under-hood TIPM. If you’re chasing an interior electrical issue (radio, power outlets, HVAC, airbag light), you will still be working at the under-hood TIPM.

Trunk/cargo fuse box

Not equipped on 2017 Wrangler JK. Tow-package modules and connectors are located behind the left rear interior quarter panel, but their fuses are still in the under-hood TIPM.

How to test a fuse

• Visual check: With the key off, remove the suspect fuse using the puller in the TIPM cover. Look through the fuse window; a broken or burned link means it’s blown. Replace only with the same amp rating and type.
• Test light method: Leave the fuse installed. Key on. Touch a test light to the two tiny test tabs on top of the fuse. A good fuse lights on both tabs; lighting on only one tab means the fuse is blown.
• Multimeter continuity: Remove the fuse and measure across the blades. 0–1 ohm indicates a good fuse; open circuit indicates blown.
• If a new fuse pops immediately, stop and diagnose the circuit for shorts to ground, rubbed wiring, or a failed component before upsizing the fuse (never install a higher-amp fuse).

Common blown fuses on this vehicle (what to check first)

• Power outlets (M6/M7 20A yellow): Phone chargers, inflators, and fridges often overload or short. Check the outlet for coins/debris and inspect the plug/cord. Verify you’re using the correct outlet (some are ignition-switched). Replace with 20A only.
• Headlamps (15A blue each side): Aftermarket LED/HID conversions or corroded connectors can spike current or confuse the TIPM. Return to stock bulbs or add a proper relay harness with anti-flicker modules if upgrading.
• Radio/Uconnect (15–20A): Look for pinched harness at the head unit, shorted USB/12V sockets, or water intrusion from a missing antenna grommet.
• HVAC blower (40A J-case): If this blows, suspect a failing blower motor drawing excessive current or a seized blower. Spin the blower by hand and check current draw before replacing the fuse.
• ABS pump (40–60A J-case): Rare to blow; if it does, inspect the pump motor for internal shorts and check ground integrity at the frame.
• Fuel pump (20A): If blown, inspect wiring at the top of the fuel tank for chafe, check the pump current draw, and verify no aftermarket accessories have been tied into the pump circuit.
• Trailer tow circuits (15–20A): Most failures trace to the trailer side—damaged 4/7‑way plug, corroded lamp sockets, or a short in the trailer wiring. Unplug the trailer and recheck.

Tip: The TIPM cover legend is your best guide to slot numbers and ratings on your exact Jeep. Jeep revised assignments across years and trims, so verify before moving fuses.
