Answer
yes, check the wiring harness where it passes through the door, you may have to remove the rubber covering, this is a spot that can cause wires to break over time by the door opening/closing, with the door panel off follow the wires to where they connect to an electrical connector in the left kick panel, disconnect the connector and check continuity for each wire to the connector on the switch, the wires are color coded so this should a relatively easy test, you may also visually inspect the wires where they go through from the door to the body, it sounds like the problem is there.
