2016-2017 Hyundai Veloster Fuse Block Harness: Solving Electrical Faults
This guide covers the specific engine bay fuse block and integrated wiring harness for the 2016-2017 Hyundai Veloster, focusing on compatibility, common failures, and replacement.
- This part (91236-2V179) is ONLY for 2016-17 Velosters with a non-turbo engine, automatic transmission, conventional key, and NO fog lights.
- No programming is required for installation; it is a plug-and-play component.
- Failure often causes multiple, seemingly unrelated electrical problems, including no-start conditions.
- When buying used, inspect carefully for any signs of melting, corrosion, or cut wires, and verify the part number matches exactly.
Key Compatibility Information
The fuse block wiring harness with part number 91236-2V179 is highly specific. Ordering the wrong part will lead to connectors that don't match or features that won't work. This part is for 2016-2017 Hyundai Veloster models with the following configuration:
- Engine: Naturally Aspirated (Non-Turbo)
- Transmission: Automatic Transmission
- Ignition: Conventional Key Ignition (not push-button start)
- Lighting: WITHOUT factory-installed fog lamps.
Warning: The most common mistake is purchasing this part for a vehicle with fog lamps. The wiring harness for models with fog lamps is different and has provisions for the additional lighting circuit. Always verify your vehicle's original options and part number before purchasing.
Symptoms of a Failing Fuse Block or Harness
A problem with the main fuse block or its integrated harness can cause a wide range of confusing electrical issues. Because it's a central component, symptoms are often not isolated to a single system.
- Multiple Unrelated Electrical Failures: Circuits like the radio, interior lights, and power windows may fail simultaneously or intermittently.
- Car Will Not Start or Cranks Intermittently: A bad connection in the fuse block can prevent power from reaching the starter motor relay or the fuel pump.
- Frequently Blowing Fuses: While a single blown fuse usually points to a problem in that specific circuit, multiple fuses blowing repeatedly can indicate a short within the fuse block or harness itself.
- Dim or Flickering Lights: Headlights or dashboard lights that flicker can be a sign of a poor connection or corrosion within the fuse block, causing a voltage drop.
- Visible Corrosion or Melting: A visual inspection may reveal green or white crusty corrosion on the terminals, or melted plastic around specific fuse or relay sockets, indicating a severe overload or poor connection.
- Buzzing or Hissing Sounds: Any audible noise from the fuse box is a sign of electrical arcing from a bad connection and is a serious fire hazard.
Known Issues, Recalls, and TSBs
While there are no recalls specifically for the fuse block wiring harness on the 2016-2017 Veloster, several related electrical system notices are relevant:
- ABS Module Recall (NHTSA Campaign 23V-651): An important recall notes that the Anti-Lock Brake System (ABS) module can leak fluid internally, causing an electrical short that could lead to an engine compartment fire. The remedy involves replacing a fuse. While not a direct fault of the fuse block, it highlights the potential for electrical issues in the engine bay.
- TSB on Anti-Theft System: A technical service bulletin was issued for some Hyundai vehicles of this era concerning the anti-theft immobilizer system. The bulletin provides a procedure to update the body control module to revise the alarm system's operation. This is not directly related to the fuse block itself but is relevant to overall vehicle electronics.
Programming and Installation
Pro Tip: This fuse block and wiring harness assembly does not require any programming, flashing, or dealer calibration. It is a direct replacement part. The vehicle's computer systems, like the ECU, may need a few drive cycles to relearn idle and fuel trims 🎬 Watch: How to reset your Veloster's computer systems after the battery has been disconnected for the replacement, but the fuse block itself is plug-and-play.
Replacement involves disconnecting the battery, carefully unplugging all connectors from the old fuse block, unbolting it from the chassis, and then installing the new one in the reverse order. It is critical to take photos before and during disassembly to ensure all connectors are returned to their correct locations.
Buying a Used Fuse Block Wiring Harness
A used OEM fuse block is an excellent, cost-effective alternative to an expensive new part. However, careful inspection is crucial to ensure you get a reliable component.
What to Inspect:
- Verify the Part Number: The most critical step. Ensure the tag on the unit reads 91236-2V179. Accept no substitutes.
- Check for Corrosion: Look closely at all the electrical pins and sockets. Avoid any unit with signs of green or white powder, which indicates water damage and will lead to future problems.
- Inspect for Melted Plastic: Carefully examine the plastic around each fuse and relay slot. Any sign of melting, warping, or discoloration means the terminal overheated due to a poor connection or a major short circuit. Do not buy such a part.
- Examine the Wiring Harness: Inspect the integrated harness for any cut wires, damaged insulation, or repaired sections. The harness should be complete and unmodified. Ensure all connector plugs are intact and not cracked or broken.
- Donor Vehicle History: If possible, choose a part from a vehicle with lower mileage and no reported flood or fire damage.

Frequently Asked Questions (FAQ)
Does this fuse block need to be programmed to my car?
No. The engine bay fuse block is a non-programmable part. It does not need to be flashed or coded by a dealer. It is a simple plug-and-play replacement, though you will need to disconnect the battery to perform the installation safely.
Can I use this part if my Veloster has fog lights and add them?
No. This part, 91236-2V179, is specifically for models that did NOT come with factory fog lights. The integrated wiring harness lacks the necessary wiring and connectors for the fog light circuit. You must purchase the correct fuse block assembly for a vehicle equipped with fog lights.
Will replacing the fuse block fix my car's no-start problem?
It might. If the no-start issue is caused by a bad connection or a failed relay socket within the fuse block that controls the fuel pump or starter, then a replacement could solve the problem. However, a no-start condition can also be caused by many other components, such as a dead battery, a bad starter, or a failed fuel pump. Proper diagnosis is key before replacing parts.
Is it difficult to replace this part myself?
For a DIY mechanic with some experience, this is a manageable job. The difficulty is moderate, primarily due to the number of electrical connectors that must be carefully unplugged and reconnected. The fuse block itself is typically held in by a few bolts. The key is to be patient, label connectors if you are unsure, and ensure the battery is disconnected before you begin.
