If you are talking about a 1st gen xB, look under the upper flat section to the right of the speedo. You will see a black phillips head screw. It is plastic and about a size 1 phillips. It will have to be short because of the angle. Hard to see without a flashlight shining on it. Also easy to strip out the head, so be careful. Once it is out, rest of the cover should pop out. It's been couple of years since I pulled one, but remember the screw can be a bugger.
