You will need to change the switch which is something you can do yourself. quite a common fault on the clios presuming its an 01 - 05 model. You need a small falt screw driver to pop the front triangle off then the switch should just pull out with a bit of a wiggle. Available from a renault dealer for around £20.00 + vat. i just replaced mine and a few customers as i work for a motor factors
hope this helps
