I recently replaced the drivers side power door lock actuator and switch with new. Does not activate.The passenger side switch activates both doors fine. Any suggestions on DS?

I believe the power door lock has constant power- have you checked for power at the switch?

Checked for broken wires in the rubber boot that goes between the door and the body?

I had that problem once and it was the light blue wire ...

HTH!

My window connector (at the switch) had a broken wire causing the same thing. You couldn't see that it was broken but measuring voltage at the switch show the problem. Once I saw it I move the wire and POP.
