If it is wired per factory there is no fuse but rather a self resetting circuit breaker. On a 23rd series it is located on the cluster approximately in the bottom middle under the gauges. If there is a problem, the breaker should cut the current and then reset after a few seconds and then trip again. It will keep this up until the problem is fixed or breaker finally fails.
There should be power all the time on one side of the breaker. The clock fuse should also be connected to that side. The other side of the breaker feeds the courtesy lights and other items such as the glove box light and brake light. If you have brake lights then the CB should be OK and the problem with the courtesy lights is somewhere else. If no brake lights then you are going to have to get under and use a meter at the breaker and see what is going on.
Here is a photo of the cluster taken by BDeB with some arrows pointing to the breaker and power in and out terminals to check with the meter.
