Question
hi...thanks for this board, its great...
my passenger side window is in up position (all way up, thank god) and drivers door window switch and in dividual front pass door window switch pushing get no response; on right rear door window, driver door master switch will make that window go down but not up, and window switch right rear door must be used to get it back up; both drivers side are fine working with both master and door switches; i am mystified...need driver master window switch replacment? or right front motor or both????  

Answer
Tony, replace the switches on the master panel.  You can buy them separately.  The individual window switches may also be dirty.  You can take them apart and clean them but not sure if you want to go through the trouble.  Sometimes the cleaning works, sometimes it doesnt.  Roger
