Is Your S80 Turn Signal Switch Failing?
When the turn signal switch on a first-generation Volvo S80 starts to fail, the symptoms are usually very noticeable. Due to wear on the internal electrical contacts, you may experience problems that come and go before the switch fails completely. It's a common issue for these cars as they age.
Common Symptoms of a Bad Switch:
- Intermittent Signals: The most common symptom is when the turn signals work only sometimes. You might have to hold the lever in a specific position to keep them blinking.
- Delayed Blinking: You may flip the switch and notice a one or two-second delay before the signal starts flashing.
- Signals Don't Work at All: The switch may stop responding entirely, even though your hazard lights still work (which confirms the bulbs are good).
- High Beam Problems: Since the switch also controls the headlights, you might find that your high beams won't turn on or won't stay on.
- Trip Computer Issues: The buttons on the end of the stalk that control the instrument cluster display may stop responding.
Check This First!
Before ordering a new part, check the fuses. A blown fuse (specifically fuse #22 or #23 in the panel) can cause identical symptoms. Some owners have also had temporary success by disconnecting the battery for 10-15 minutes to reset the car's electronic modules.
Choosing the Right Aftermarket Switch
For your 1999-2004 S80, you have a choice between Genuine Volvo parts and aftermarket options. While Volvo owners often prefer Genuine parts for critical electronics, the turn signal switch is a simple enough component that a quality aftermarket part is a reliable choice.
Brand Tiers:
- Genuine Volvo: This is the original part made for your car. It guarantees perfect fit, color match, and function. For the 1999-2003 models, the original color was grey, while 2004 models used a black/charcoal switch. The parts are interchangeable, so the color is the only difference.
- Standard Ignition (SMP): A well-regarded aftermarket manufacturer. Their parts are designed to meet or exceed original equipment (OE) specifications for fit and performance, often using quality materials like copper alloy conductors for longevity. This is a solid choice for a balance of quality and price.
A Note on Part Numbers
Volvo used different part numbers depending on the model year and whether the car was equipped with a trip computer. Always verify the part fits your specific S80 using the VIN or by matching it to your old part. Common part numbers include 31268575 and 31268566.

Frequently Asked Questions
Is this a difficult repair to do myself?
No, this is a very easy DIY repair. The entire job can be done in under 30 minutes with basic tools. You only need to remove the plastic covers around the steering column (held by three T25 Torx screws) and then two Phillips head screws that hold the switch itself. The switch then unplugs and slides out.
Do I need to remove the steering wheel or airbag?
No. Unlike replacing the clock spring or the entire steering module, you do not need to remove the steering wheel or airbag to replace just the turn signal stalk. This makes the job much safer and simpler for a DIYer.
Will the new switch need to be programmed by a dealer?
No, this part is a simple plug-and-play component. No software download or programming is required after installation.
Can I just clean my old switch instead of replacing it?
Sometimes, yes. The failure is often caused by dirt or old grease on the internal copper contacts. It is possible to carefully open the switch housing, clean the contacts with contact cleaner or rubbing alcohol, and re-grease them with dielectric grease. However, if the contacts are too worn or the plastic is broken, replacement is the only option.
