Hi, I have a Renault Clio 1996 N reg 1.4RT. The speedometer has stopped working, it worked intermittently but now has stopped altogether. I took the dashboard off and manually tried the speedo, which worked fine so I know it has not broken.The cable was attached but I do not know if it has broken. Any ideas on what it could be and how much it would cost me to fix? Many thanks, Ryan.
