    2003 Honda Odyssey Front door lock problem
    Hi, I have a very specific problem with my 2003 Honda Odyssey. My driver side door lock no longer works with the remote, however the other doors do. It still manually locks and unlocks (depressing the tab). When you manually lock the door, the other doors lock as well (using the up/down tab). However, when you manually unlock the door, the others do not. I have replaced the passenger side multiplex unit which is often the culprit, but this did not solve the problem. In addition, I have checked the door actuator and found it to be fine. I bought a new door actuator and hooked it up. Same result. I put a volt meter on the connection to the door actuator and when using the door lock button, I get very low voltage to the connection. In addition, prior to depressing the door lock button, I am reading zero voltage at this connector.

    Can you help out?

    Thanks,

    Kevin

    The thing with multiplex switches is that they do operate on only 1-2v. They send a signal to the body computer, which in turn sends 12v to the switch. Put the meter across both pins in the actuator connector, not to ground, then cycle the switch both ways. It should show 12v one way and -12v the other. If not, a common problem is a bad wire in the fraim where the wires go from the door to the body.
