Why is my Volvo S60 display not working?

If the display is not working in Your Volvo S60 it could be caused by one of several things. You should check Your fuses first before trying to diagnose the cause. Check with Your owners manual and turn to the fuse diagram page to locate the fuse that operates the display. Pull it out of his cavity and hold it up to the light and look at the filament on the inside. If the filament is blown, replace with a flat blade style fuse that has the amperage rating. If the fuse is OK, it could mean that there is a wiring issue. The wiring connector on the backside of the head unit could either be unplugged or have a damaged pin in the connector.
