Replacing the Turn Signal Switch in Your 1986-1992 Jeep Comanche
Don't let a faulty switch sideline your truck; here's what you need to know to get your signals, wipers, and high beams working again.
- The turn signal switch is a multi-function unit controlling signals, headlights, and often wipers/cruise.
- You MUST verify if your truck has a tilt or non-tilt steering column before ordering a new part.
- Standard Ignition is a community-recommended brand for quality and longevity over cheaper economy parts.
- Replacement requires special tools like a steering wheel puller and lock plate compressor.
Is Your Comanche's Turn Signal Switch Failing?
Because the turn signal switch on the 1986-1992 Jeep Comanche controls multiple systems, a failure can show up in several ways. The plastics inside the switch become brittle over time, and electrical contacts wear out. Watch for these common symptoms:
- No Turn Signals: The most obvious sign is when your turn signals don't work at all, either on one side or both.
- Signals Won't Stay On or Cancel: The lever may not 'click' and stay in position, or it may fail to cancel after you complete a turn. This points to mechanical wear inside the switch.
- High Beam Problems: You might find yourself unable to switch between high and low beams, or the high beams may be stuck on.
- Hazard Lights Don't Work: The hazard button is integrated into the switch assembly, and its failure is common. This can sometimes affect brake light operation, making it a serious safety issue.
- Erratic Wipers or Cruise Control: If your switch includes these controls, you may notice the wipers behaving strangely or the cruise control failing to engage.
Important Note on Replacement
Replacing the turn signal switch on a Comanche requires getting inside the steering column. You will need special tools, specifically a steering wheel puller and a lock plate compressor tool. This job is more involved than a simple plug-and-play swap.
Choosing the Right Aftermarket Switch for Your Comanche
Original Mopar switches are long discontinued, so your only option is the aftermarket. Quality can vary significantly between brands, so it's important to choose wisely.
Premium Aftermarket (e.g., Standard Ignition)
Brands like Standard Ignition (also known as Standard Motor Products or SMP) are highly regarded in the Jeep community. They use better materials, such as durable copper alloy conductors, and their parts undergo rigorous testing to ensure they fit and function like the original. While they cost more than economy options, they are known for reliability and longevity, making them the recommended choice to avoid doing the job twice.
Economy Aftermarket (e.g., Replacement)
Economy or 'value' brands are the most affordable option and will get your truck back on the road. However, forum users frequently report issues with these cheaper parts, including poor fitment, incorrect wire colors, and a much shorter lifespan. If you are on a tight budget, an economy part can work, but be prepared for the possibility of replacing it again sooner than you'd like.
Pro Tip: Tilt vs. Non-Tilt Column
The single most important detail when ordering is whether your Comanche has a tilt or non-tilt steering column. The switches are different and are not interchangeable. A tilt column has a separate lever on the left side that allows you to adjust the steering wheel's angle. Double-check your truck's configuration before you buy.

Frequently Asked Questions
Is this a hard job to do myself?
It's moderately difficult due to the need for special tools (steering wheel puller, lock plate tool) and the careful work required inside the steering column. If you are a confident DIYer with the right tools, it's very achievable. Otherwise, a professional mechanic can do it in 1.5-2 hours.
My wipers are acting up, but the signals work. Is it the switch?
Yes, it's very likely. Since the wiper controls are often part of the same multi-function switch, erratic wiper behavior is a common symptom of the switch failing internally, even if other functions still work.
What is the difference between a switch for a tilt and non-tilt column?
The mounting points, shape of the housing, and sometimes the wiring harness length are different to accommodate the tilting mechanism. They are not cross-compatible. You must order the specific switch for your column type.
Why not just get a used one from a junkyard?
You can, and it's a cheap option. However, these switches fail due to age and wear. A used part from another 30+ year-old truck is likely to have the same brittle plastics and worn contacts as your old one, and it may fail shortly after you install it. A new, quality aftermarket part is a more reliable long-term solution.
Technical Specifications
OEM Part Numbers: 56002011 25111262
The Jeep Comanche uses a GM-style Saginaw steering column, so many internal parts are shared with GM vehicles of the same era. The most critical specification is confirming fitment for a tilt vs. non-tilt column and whether the switch needs to support delay wipers and/or cruise control. Always verify by application, not just by part number.
