To check the fuses on a Volvo V70, first locate the fuse box, which is typically found under the dashboard on the driver's side or in the engine compartment. Remove the fuse cover and use a fuse puller or pliers to carefully extract the fuses you want to check. Inspect each fuse for a broken filament or discoloration; if it's damaged, replace it with a new fuse of the same amperage. Always refer to the owner's manual for the specific fuse layout and ratings.
In the '99 V70, its under the front hood between the windshield and left front wheel well.
Check the setting on the switch
Check the owner's handbook.

The rear wiper relay on a 2005 Volvo V70 is typically located in the under-hood fuse box. To access it, open the hood and locate the fuse box near the driver's side. The relay itself may not be distinctly labeled, so consulting the owner's manual for the specific relay position can be helpful. Make sure to check the relay and surrounding fuses if you are experiencing issues with the rear wiper.
