Is Your Turn Signal Switch Failing?
A common issue on the 2003-2007 Volvo XC70 is an intermittent or failing turn signal switch. Often, the first sign of trouble is the left turn signal acting up. You might find that it doesn't work unless you jiggle the stalk or hold it down with extra pressure. This happens because the electrical contacts inside the switch wear out over time. Before you spend money on a new part, some owners have had success cleaning these internal contacts as a temporary fix.
Common Symptoms of a Bad Switch:
- Turn signals work intermittently or not at all.
- The signal won't stay on without holding the lever down.
- High beams cannot be activated or switched off.
- The trip computer buttons on the stalk stop responding.
- You hear no clicking sound from the dashboard when the signal should be on.
Choosing the Right Aftermarket Part
When it's time to replace your switch, you have a choice between Genuine Volvo parts and aftermarket alternatives. For this specific part, the decision is straightforward.
- Genuine Volvo: This is the original part your car was built with. It guarantees perfect fit and function. Many owners prefer to stick with Genuine parts for electronic components to ensure compatibility.
- Standard Motor Products (SMP): Standard is a well-regarded aftermarket brand that produces parts designed to meet or exceed original equipment (OE) specifications. Their switches are made to be direct-fit replacements, meaning they should install and function just like the original without any modifications. For a component like this, a quality aftermarket brand like Standard is a reliable and cost-effective alternative to the Genuine part.

Frequently Asked Questions
Can I fix my old switch instead of replacing it?
Maybe. Many owners report successfully cleaning the internal contacts of the switch to restore function, at least for a while. This involves removing the switch and carefully cleaning the small circuit board inside with a pencil eraser and electrical contact cleaner. 🎬 See how to clean and repair your original blinker switch. It's a free fix if you have the time and can be a good first step before buying a new part.
Do I need to disconnect the battery for this repair?
While not always strictly necessary for a simple part like this, it is always a best practice to disconnect the negative battery terminal before working on any part of your vehicle's electrical system. This prevents accidental shorts that could damage more sensitive components.
Are there any recalls for the turn signal switch on my XC70?
No, there are no specific recalls for the turn signal switch on the 2003-2007 Volvo XC70. A recall in 2013 for 2014 models mentioned turn signal failure, but it was related to the Central Electronic Module (CEM) and does not apply to this generation.
Why does my turn signal blink fast?
A fast-blinking turn signal is your car's way of telling you that a bulb has burned out. The change in electrical resistance from the bad bulb causes the flasher relay to blink faster. This is not a symptom of a bad turn signal switch. Check your front and rear turn signal bulbs first.
