2002 Volvo S60 Display

You should take it in to Volvo. Sounds like the cluster itself may be going bad? You can remove it yourself and check that the connectors are making proper contact but if the cluster needs to be replaced then Volvo will need to replace it since they need to load the software an enter important information like the right mileage you have now, tire size for the speedo to be accurate. Either way they need to diagnose to make sure tht is the problem and not a problem with the low speed CAN BUS? Do you also have SRS and maybe ABS light on as well?
