I Know there are a lot of these windows posts on here, but I could not find one, on here or google, that helped me. Me and my girlfriend have just bought a 1.5 Renault Megane Dynamique. It has run into an issue within its first week. From day 2 the front passenger window has played up. It worked at first, then it wouldnt go back up from a partially opened position. Then once it was up we didn't try it for a day. Then it wouldnt go down. These troubles have persisted so far and I was wanting to find out any possible causes before taking it back to the dealer next week.

Thanks for reading and any help.
