no exactly. see, out of your door there is two wires that run into the car under the dash. they are running to your cars relay that works for your door locks. one wire is for the door lock open, and the other is lock close. now, when you activate the switch on your door, its actually giving one of the wires(either lock or unlock) that run under your dash a ground. that ground is, again, for a relay that will activate the door locks.
sometimes these wires(lock and unlock) don't leave the drivers door because sometimes the door locks are controlled by a module in the drivers door that also may work to control your windows. this is not on all cars, but many have this setup.
btw, thanks, i try to be helpful, sometimes i can but sometimes i can't. just another day as a HAN member...
