2004 four door ram 1500 windows only row down from master switch. some days work. most of time not

Check for a broken wire(s) inside of the weather boot that runs between the drivers side door and the body of the vehicle, and also for a broken wire at the wire connector to the master window switch on the drivers side door. Any broken wires that are found should be soldered back together well and do not use wire connectors. If you need to lengthen a wire be sure to use the same gauge wire as the one that you are trying to repair.
