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?

Attached is the wiring diagram.

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

I yhink the issue is there but cant be sure being as you are there and I am not to test and confirm.

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?

You may be right but I am going on your symtoms and your info with the wiring diagram.

I wish I could be more positive but without me touching it, I cannot be certain. Just a educated guess on my expierence

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.
