I think the wife spilled something on the driver's door power window control box. So now, the rear passenger side window can't be rolled down from the driver's door contol box. :| Well, I've been able to do it a couple of times when I push down and backwards. Anyhow, I do think that it got slightly gummed up in there. I'm thinking I can take the whole unit apart ... not sure what to clean it up with. Thoughts? Wonder if I can just spray something on there too see if it breaks up before I tear it apart.
