Why don't my speedometer work while I am driving my 1992 Cadillac Brougham?

If your speedometer isn't working in your 1992 Cadillac Brougham, it could be due to a faulty speed sensor, a broken speedometer cable, or a malfunction in the instrument cluster itself. Check the speedometer cable connection to ensure it's secure and not damaged. Additionally, issues with the vehicle's electrical system or blown fuses may also affect the speedometer's functionality. If the problem persists, it may be best to consult a mechanic for a thorough diagnosis.
