I had a similar problem as KC Dave. Window would only go up with the passenger switch, but worked fine from the master switch. Suspected the switch. Swapped switch with one from rear door, but the problem remained. Then I noticed one of the metal connectors in the wiring harness had broken in two. I was able to remove it and resolder it back together and all is good now.
It does sound like your switch is bad, but just in case the cleaning doesn't fix it, check the wiring harness connector.
