You may think it should be a bad switch or motor. We will hook up our lap top and read the codes and you’ll see that there is what’s called CAN communication issues as well as mechanical/electrical faults to look for. It could take considerable time to figure out if the control module under the seat is bad (possible water damage) or the one in the door itself. It may also be the wiring that is broken where the door hinges, that open and close 3 million times in a cars life. All this has to be determined before condemning a switch or motor. If that isn’t confusing enough for you, the answer to this particular question, in at least one instance was that the control module in the right rear door was bad and this kept the driver’s window from working. No need to scratch your head when hearing that sound for the first time, that’s why we are here to figure these things out for you.
