* In the passenger compartment fuse box: This is the most common location. The passenger compartment fuse box is typically located under the dashboard, often accessible by removing a cover on the side of the dash near the passenger's feet. Check the fuse box diagram (usually located on the inside of the cover) to identify the relay. It's often labeled as the blower motor relay or a similar designation.
* In the relay box near the battery (under the hood): While less common, some Volvo 850s might have it here. Again, checking the diagrams for the relay box is essential.
To find it definitively:
1. Consult your Volvo 850's owner's manual: This is the best resource for the precise location.
2. Check online forums and resources: Websites dedicated to Volvo 850s often have detailed information and photos from owners who have located the relay. Search for "Volvo 850 blower motor relay location" or similar.
3. Look for a relay with a similar size and shape to other relays in the fuse boxes: Blower motor relays are usually fairly large compared to smaller relays for other circuits.
Remember to disconnect the negative battery terminal before working with any electrical components to avoid short circuits.
