Turn the wheel all the way to the left until it can't go any further, and apply as much force to the bolt as possible. If it still won't move, you can try applying heat to the bolt with a torch, being careful not to burn anything.

Once you loosen the bolt, mark the steering wheel's position relative to the spline it's on, and remove it. This will allow you to ease the instrument cluster out-- ideally using plastic tools that are specifically made for doing so. Be careful not to pull the cluster out too hard or too far, though, because the attached wires aren't long enough to pull it out very far without detaching the wires.

Good luck,
