After cleaning, did you confirm the operation of the passenger side switch using a continuity tester? In the up position, blu/wht is connected to blu/blk. In the down postion blu/red is connected to blu/blk.
If the passenger window operates fine in both directions from the driver side door switch, there is most likely still a problem with the passenger door switch. If the passenger door window switch tests out fine, with the ignition switch in the run position check for voltage on the blu/blk wire on the door harness side of the plug that connects to the switch. There should be +12v on that wire with the ignition in the run position. If you don't have +12v on that blu/blk wire you may have a wiring harness problem which would be a major hassle. Hope that the problem is the switch!
