Question about Cars & Trucks
Three doors open&lock.....R-rear passenger door does neither ,also window inoperable.,checked fuses/O.K..Any common culprit?
There is a wire harness that plugs the door into the car. If you open the door you will see a black accordion boot that goes from the door to the body of the car. If you remove it from where it attaches to the car there should be a plug inside of the hinge pillar. make sure this is plugged in.

first check or replace the relays in the fuse panel under the dash for those two circuits and see if that fixes it

sounds like that rear door lock will also not unlock with the switch either, correct ? It might lock , but not unlock. Door lock actuator needs to be replaced.

Have you tried to open it from the back seat? If you have then you will have to take off the cover on the door and there should be a release button. Most covers are easily removed with a flat head screw driver - If your door requires a motor to operate than that is your problem. Hope this helps.

Not sure if they are same on 2006 but there should be a couple of small rounded metal contacts, or similar, on door that meet with door post to complete the connection. When you find them, clean them off with a little fine steel wool or SOS pad, minus the soap, and see if that doesn't cure it.

Do you know about computer controlled power windows ?
Power Windows Operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally to its associated door. The driver door window can be operated only from the driver door window switch built into the DDSA.
When a window is operated from the DDSA, the DDSA interprets the window switch signal as a specific window switch request and sends the information to the driver door module (DDM) via the power door serial data circuit. The DDM examines the request and checks to see if it has received any class 2 serial data messages from any of the other vehicle modules (i.e. ignition switch position) prohibiting the movement of the window. If the window being operated is the driver door window, and if no prohibitive class 2 messages have been received, the DDM then applies voltage and ground to the driver door window motor to move the window glass as requested. If the window being operated is a passenger door window, and no prohibitive class 2 messages have been received, the DDM sends the request, via the power door serial data circuit, to the appropriate passenger door module. The passenger door module then applies voltage and ground to the passenger door window motor to move the window glass as requested.
When a passenger door window is operated from the power window switch mounted locally to its associated door, the passenger door module first checks to see if the DDM has received any prohibitive class 2 serial data messages. If there are no prohibitive messages, the passenger door module powers the associated passenger door window motor.
Both front door windows have the express down feature. This allows the front door windows to be fully opened by momentarily pulling the appropriate window switch lever to the second detente and then releasing.

Class 2 and Power Door Serial Data Links
The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible.
Your best bet is to take it to the dealer or an ASE certified repair shop .
