My front passenger side window has started to get a mind of its own and either winds itself down all by itself, or wont wind back up until I power of the ignition.
It doesnt seem to be related to anything, like shutting the doors or going over bumps etc it just does it one or twice a day.

Any ideas what needs replacing?, I dont think its the switches as when it goes down neither the drivers switch or passenger door switch will bring it back up again until the ignition is switched off and back on again
I dont mind it now whilst the weather is good but I dont fancy driving down the motorway in the rain.
