Hi all, when I bought my 2003 Sport TDCi last month the passenger side electric window would go down but wouldn't go up using the passenger switch.

Now it won't go down or up via the passenger switch and sometimes it won't budge using the driver-side switch either.

It seemed like it could just be an issue with the passenger side switch contacts or something, but with it occasionally not working using the driver's side button I'm now not so sure and wonder if it's in fact a motor problem.

Anyone got any ideas?
