First off disconnect the battery. You'll obviously need to get the instrument cluster out. It should just have a few screws at the top, then it'll slide out allowing you to disconnect the wires. It be wise just to replace all of the bulbs while you are in there. http://www.pelicanparts.com/BMW/techarticles/101-Projects-90-Gauges/101-Projects-90-Gauges.htm That gets pretty detailed for the E36's.
If you cannot see the odometer reading on a 1991 BMW 525i, it could be due to a faulty odometer gear, a burned-out bulb, or a malfunctioning instrument cluster. First, check the dashboard lighting to ensure it's not simply dim. If the lights are functioning, you may need to inspect or replace the odometer gear, which is a common issue in older BMWs. If you're unsure, consulting a mechanic or a specialist in vintage BMWs may be advisable.

To repair a non-lighting odometer on a 1998 BMW Z3 Roadster, first check the fuse related to the instrument cluster, as a blown fuse can cause the odometer light to fail. If the fuse is intact, you may need to inspect the instrument cluster for loose connections or damaged wiring. In some cases, the odometer's internal bulbs may need replacement; disassemble the cluster to access and replace them. If these steps do not resolve the issue, consider consulting a professional, as the problem could involve a faulty circuit board.
