I know they go bad, this is a used one from ebay about a year ago. I'm going to do the s.steel fab on the DHC so it wont' break again. Time to sell this beast, need better dependability.

So I am CURRENTLY having a similar issue on mine. Unless I have the window lock engaged on my master switch, the rear right passenger window will always roll down with key on. The front window switches run on LIN I think, which is causing this issue. I made sure to check the rear passenger window switch and clean it. But I haven't cleaned the master window switch.
