CHEVY POWER DOOR LOCKS

2000 Chevrolet Astro

Electrical problem
2000 Chevy Astro 6 cyl Two Wheel Drive Automatic 45000 miles

The driver and passenger door will not automatically lock or unlock only the rear and side door work. I measured the voltage going to the door lock motor on the passenger door and was able to meter 12 volts when the door lock button was actuated so I though the motor was bad. I replaced the motor and it still does not work. Any advise is appreciated.

Hello jedenco

you got 12 volts on power side,check also the ground side. (G200) and the splice before the ground.
The problem is likely with the splice S229.
I'm sending the diagram to help you identify the wiring.
