2001 ford focus

Hello I'm working on my mothers ford focus 2001. I can't seem to locate door pin wire for the passenger and rear doors. It says black with blue. In drivers kick panel. I've tested 3 wires black with blue black with orange and black with red. They read 12 volts whether doors or opened or not. Found black w yellow drivers in kick and it works fine. Maybe i should go directly to switches. Any advice ? Thanksbat9905

if a wire tests it should be fine.
