Key Takeaways
  • A failing headlight switch is a common issue on 1987-1994 B350s, with symptoms like flickering lights or total failure.
  • Replacement is a straightforward DIY job that requires removing some dash trim for access.
  • Standard Ignition (SMP) is a highly-regarded aftermarket brand for this part.
  • If a new switch doesn't fix the issue, investigate fuses, grounds, and the floor-mounted dimmer switch next.
The headlight switch in your 1987-1994 Dodge B350 is the main control for your vehicle's exterior and interior lighting. It's a pull-knob switch located on the dashboard. Pulling it out to the first position activates your parking lights, taillights, and instrument panel lights. Pulling it all the way out turns on the main headlights. The switch also typically includes a function to adjust the brightness of your dashboard lights by twisting the knob.

Is Your Dodge B350 Headlight Switch Failing?

On these classic Dodge vans, the headlight switch is a common wear item. Over time, the internal contacts can burn out or the plastic components can become brittle and break. This can lead to a range of frustrating and dangerous lighting problems. Recognizing the signs early can save you from a breakdown in the dark.

Common Failure Symptoms

  • Intermittent Headlights: Your headlights or dashboard lights flicker or turn off by themselves while driving. Wiggling the switch might temporarily fix the problem.
  • No Headlights or Taillights: You pull the switch, but some or all of your lights don't turn on at all. This could affect headlights, taillights, or dash lights independently.
  • Switch Feels Spongy or Doesn't "Click": A good switch has distinct clicks for each position. A worn-out switch may feel mushy or have no defined stops.
  • Only High Beams Work (or vice-versa): While sometimes related to the dimmer switch on the steering column, a faulty main headlight switch can cause issues with selecting high or low beams.
  • Burning Plastic Smell: A strong indicator that the switch is overheating and melting internally, which poses a fire risk.

Choosing the Right Aftermarket Headlight Switch

For a vehicle of this age, finding a new OEM (Original Equipment Manufacturer) part from Mopar is highly unlikely. The good news is that the aftermarket provides reliable and affordable solutions. The key is choosing a quality brand.

  • Standard Ignition (Standard Motor Products): Often considered a top-tier aftermarket brand, Standard Ignition (SMP) parts are known for meeting or exceeding OEM specifications. They are a trusted choice for electrical components and a solid bet for your B350.
  • Rostra Powertrain: Rostra is a well-known manufacturer that produces a wide variety of automotive parts, including electrical components. While they are a reputable company, Standard Ignition is generally more specialized in switches and sensors.

Pro Tip: Given the similar price point, the Standard Ignition switch is generally the recommended choice for durability and reliability in this specific application.

How Much Does a New Headlight Switch Cost?

Replacing the headlight switch on your B350 is one of the more affordable repairs you can undertake. The parts are not expensive, and if you do it yourself, you can save a significant amount on labor.

Part/Service Estimated Cost
New Aftermarket Headlight Switch $35 - $59
Shop Labor $90 - $150
DIY Total $35 - $59
Shop Repair Total $125 - $209

Frequently Asked Questions

Is replacing the headlight switch a DIY job?

Yes, for most owners with basic hand tools. The process involves removing some dashboard trim panels to access the switch. You'll need to disconnect the battery, remove the knob and shaft (there's a release button on the switch body), unscrew the switch from the dash, and unplug the electrical connector. The biggest challenge is often dealing with old, brittle plastic dash parts, so be gentle.

My lights still don't work after replacing the switch. What now?

If a new switch doesn't solve the problem, check other related components. The issue could be with the floor-mounted high/low beam dimmer switch, corroded headlight socket connectors, a bad ground wire, or a faulty fusible link in the engine bay. Start by checking fuses and using a test light to verify power is reaching the switch connector.

Are there any recalls for the 1987-1994 B350 headlight switch?

Searches for this specific year range did not turn up any official NHTSA recalls for the headlight switch. There was a recall for later model Dodge Ram trucks and vans (NHTSA Campaign #99V024000) for a similar issue, but it does not officially cover the 1987-1994 B350.

Why do my dash lights dimming not work correctly?

The dimming function is controlled by a rheostat built into the headlight switch. When this part of the switch fails, you may lose the ability to adjust the brightness of your instrument panel. In some vehicle models, running the dash lights at a dimmed level can cause the switch to heat up and fail prematurely. Replacing the headlight switch assembly will fix this problem.
