I have a 1991 Peugeot 405S and the speedometer just stopped working. I was wondering if im able to fix this myself and how Please Help.?

You can likely fix the speedometer yourself by checking a few common issues. First, inspect the speedometer cable for any breaks or disconnections, as this can prevent the speedometer from working. Also, check the vehicle's speed sensor, which may need cleaning or replacement. If those components seem fine, consult your vehicle's manual for further diagnostic steps or consider seeking assistance from a mechanic if you're unsure.
