If you have continuity from the DLC back to the PCM on all the pins that it should, and the PCM has power and ground everywhere it is supposed to, you probably need a PCM. Before I throw a PCM at it though, I would make extra sure that you have checked all of the stuff that I spoke of first. Remeber the PCM will have more than one power and more than one ground input.
Bad fusable link?
Check the fuses.
Have you checked the fuses?
When power doors fail on a 1999 Honda Civic there is a problem with a actuator or wiring. The door lock fuses should be checked. If the fuses are fine then the actuators themselves will need to be checked.
Just a thought have you checked the fuses?
only thing left to check is the light switch
Have you checked the relays?
Not knowing what you've done so far, have you checked your fuses yet ?
i had same problem with my 2003 Taurus on my driver's door. I got a new power window switch for $40. you should check your fuses first.
Perhaps a bad ground?
The motors that make these operate may be worn out and need replacing.
