It could be:
* Under the dashboard: This is a common location in many vehicles, including some Volvos. You might need to remove panels to access it.
* In the fuse box: Some Volvos integrate the flasher relay into the main fuse box, either under the hood or inside the cabin.
* Behind a panel in the center console: Less common, but possible on certain models.
* Integrated into a body control module (BCM): Modern Volvos increasingly use BCMs which handle many functions, including turn signals. In this case, there's no separate flasher unit to replace.
To find it, you'll need to:
1. Consult your Volvo's owner's manual: This is the best place to start. It should have a diagram of the fuse box and potentially other locations for relays.
2. Search online forums specific to your Volvo's year and model: Owners of your specific car are likely to have discussed this and may have pictures. Try searching "[Your Volvo Year and Model] flasher relay location."
3. Check online repair manuals: Sites like Haynes or Chilton offer repair manuals (often paid) with detailed diagrams.
Without knowing the specific year, make, and model of your Volvo, it's impossible to give a precise location.
