Hi there,

If all fuses and globes are ok, check the brake light switch. Now i am no Volvo expert, but i would expect it to be where everyone else puts it, and that's on the brake pedal up under the dash, there should be a micro switch with 2 wires remove wires and join (Ignition on), if lights come on replace the switch.
