drivers side? common problem on mk 2 ph1 clios. I had to change mine a little while ago, got it from eBay about 80 quid with p&p, took a little while to work out how the door panel come off prob about 5-10 and your'll have that regulator out, but its very easy once youve done it once. Another 5 mins putting the new one in(includes missing a bolt or something the first time) then a couple of mine getting the door panel back on. 20-30 mins in all, helps to have a bit of help too.
