Replaced rear door; electric lock, window, and bottom speaker not working

The Electrical Wiring Diagram (more info) shows one connector, PS1, that attaches the Rear Door No. 1 Wire harness to the Floor No. 2 Wire harness. Is it securely connected?

If so, I’d suggest using the EWD to troubleshoot one system at a time: see the pages for “Door Lock Control,” “Power Window,” and “Audio System” in the System Circuit section. Keep in mind that the ground wires from the door lock motor, power window switch, and power window motor assemblies are spliced together.

For Prius cars, the VIN doesn’t encode the trim level and options. As shown in catalog Figure 82-02, Wiring & Clamp, there are two versions of the Rear Door No. 1 Wire: 82153-47140 for cars with one speaker in the door, and 82153-47150 for cars with two.

Since the quick disconnect wiring harness wasn’t mentioned, you should connect harness to their respective connectors. If no luck, clean the contacts in the connectors.

 

If you’re trying to extract terminals from a connector, see the “Terminal and Connector Repair” section of the Wire Harness Repair Manual (PDF).

Check that the window lock switch in the driver’s door (Owner’s Manual (PDF), page 99) isn’t engaged. If that wasn’t the problem, you might need to do the power window control system initialization procedure (Owner’s Manual, page 100)—but if the window won’t go up or down at all, that’s probably not the cause. Be sure to try from both the driver’s switch and the one in the door.

With the window lock switch off, and the car in READY, the LEDs in the switch assembly in the door should be illuminated. (Compare with the other side.) If not, check power and ground at the window regulator motor assembly, connector P4. There should be about 12 V between terminal 2 (red wire) and body ground, and less than 1 Ω between terminal 1 (white wire with black stripe) and body ground. If there’s no battery voltage, check the 25 A DOOR RR fuse in the Instrument Panel Junction Block (Owner’s Manual, pages 471 and 477–478).

If that’s all OK, and the rest of the wiring is as shown in the EWD, then the next step would be to check the LIN bus connection to the Multiplex Network Master Switch Assembly, Toyota’s name for the window and door lock switch panel in the driver’s door. This requires a Toyota Techstream diagnostic system or equivalent.

The Power Window Control System section of the Repair Manual (more info) has further diagnostic procedures.
