cruise control quit on 1990 BMW 325i

cruise control was working fine no problems at all but suddenly quit.

Asked by for the 1990 BMW 325i
It might be a battery issue, and not the battery in the trunk. The rechargeable battery in the instrument cluster might be bad. If this is either discharged, or just bad, your cruise control won't work
