My 2002 c70 convertible right rear window will only lower with the "all up/down"button on the driver's door. The individual switches in the back seat and on the driver's door to that window will raise but not lower right rear window. Is there a relay or control module and should I be concerned that it will fail and leave the window stuck?

there is a control module in the master switch from the looks of it.

Thanks for the reply,
So you would think that if I replaced the master switch on the driver's door it would fix the problem?
Is the fact that it is a convertible make it possible that the module is somewhere else, as it has to somehow interact with the switch that retracts the top?

Thanks again Roy,
Is there any easy way to test the switch? Does it require any special equipment?

a scan tool can scan the bcm to monitor the actions of the windows looking for the up and down commands/

Since I don't have a scan tool and don't think I know what the bcm is it looks like someone else is going to have to check it. I appreciate your help Roy.
