Ah. Im on the south coast. Yeah it was for one side. When it first started happening I did the same as you, checked all the fuses, swapped out the switches with a mates, etc. which made sure it was the motor. Then I asked the renault dealer how much and ran away. Then I scoured the yellow pages for an independent renault specialist garage & gave them a call. They initialally said it would cost about 150- 200 notes if they used a genuine bit, but offered the idea of fitting a scrappy one. It only took 10 mins ringing round to get a motor (which had a 3 mth warranty with it). Are there any independent garages that specialise in renaults near you? Its got to be worth a go to save a few quid. Incidently I sold the rsi about a year after it was fixed & it was still fine then.
