A Practical Guide to the 1997-2005 Mitsubishi Eclipse Turn Signal Switch
If your Eclipse's turn signals are acting strange, the fix is easier and cheaper than you think.

- Replacement is an easy DIY job that requires only a screwdriver and less than an hour.
- The part is different for 1997-1999 (2G) and 2000-2005 (3G) models, so ensure you order the correct one for your year.
Is Your Eclipse Turn Signal Switch Failing?
A bad turn signal switch in the 1997-2005 Eclipse causes very specific and annoying problems. The internal plastic and metal contacts wear out over time. This can lead to some strange electrical behavior. Many owners report that a turn signal will stay on constantly, even when the lever is in the neutral position. Others find their headlights refuse to turn off, draining the battery.
Common Failure Symptoms
- One or both turn signals do not light up.
- Turn signals stay on and will not shut off.
- The signal does not automatically cancel after you complete a turn.
- You have to hold the lever in place for the blinker to work.
- Your headlights will not turn on or, more commonly, will not turn off.
- Your hazard lights work, but the individual turn signals do not.
Choosing the Right Aftermarket Switch
When buying a new aftermarket switch, you have a few quality tiers to choose from. For a part you use every time you drive, choosing a quality replacement can prevent you from having to do the job twice.
Premium Aftermarket Brands
Brands like Standard Ignition (Standard Motor Products) and Beck Arnley are top-tier aftermarket choices. They have a strong reputation for quality and durability, often meeting or exceeding the original factory part's performance. These are excellent options if you plan on keeping your Eclipse for a long time and want a reliable, long-lasting repair.
Value-Oriented Brands
Brands like Replacement and Rostra Powertrain offer a more budget-friendly solution. These parts will get the job done and are a great choice if you need to fix your car on a tight budget. While they are perfectly functional, their internal components may not have the same lifespan as the premium brands. However, many owners have successfully used budget-friendly parts to solve their turn signal problems.
Pro Tip: There was a recall related to the multi-function switch levers breaking over time. This is a known weak point. Investing in a quality aftermarket part from a brand like Standard or Beck Arnley can provide a more robust and durable lever than the original.

Frequently Asked Questions
Is this a difficult part to replace myself?
No, this is a great job for a beginner. The replacement only requires a Phillips screwdriver and about 30-60 minutes. You need to remove a few screws holding the plastic covers around the steering column, unplug two wire harnesses from the old switch, unscrew the switch itself (usually two screws), and then install the new one.
Is the turn signal switch the same for all 1997-2005 Eclipses?
No. The part is different for the 2G generation (1997-1999) and the 3G generation (2000-2005). While they look similar and install in the same way, their wiring and mounting points are not the same. You must order the switch that is specific to your car's year. For example, the OEM part number for 1997-1999 models is MR277924.
My hazard lights work but my turn signals don't. Is it still the switch?
Yes, this is a classic symptom of a failed turn signal switch. The hazard lights operate on a slightly different circuit, so when they work and the turn signals don't, it almost always points to the switch on the column being the problem.
Could my problem just be a fuse or relay?
It's possible, but less likely given the common failure symptoms in these cars. The flasher relay is a separate component, but issues like a signal staying on constantly or headlights not turning off are directly linked to the mechanical and electrical contacts inside the switch assembly itself. If you experience these specific issues, the switch is the most probable cause.
