Honda Ridgeline Rear Window Motor Cable Breaks: Replacing the Center Sliding Glass Regulator Panel
There’s a specific kind of frustration that comes from pressing the button for your Ridgeline’s rear sliding window and hearing nothing but the whir of a motor that’s not moving anything.
You know the feeling. You’re about to haul something long in the bed and want that fresh airflow, but the center glass just sits there. The good news is that when a cable breaks, you don’t need to replace the whole window —you just need the motor and cable set.
What Breaks and What You Need
The part you’re looking for is the Window Regulator, Motor Cable Set. For 2017-2025 Ridgelines, the genuine Honda part number is 73221-T6Z-A11 .
Here’s a pro tip that’ll save you some cash: The motor and cables come as one assembly . The part notes explicitly say “Includes Window Motor And Cable” . So if a cable snapped, you’re replacing the whole unit—not just one piece.

Why It Happens
Window regulators fail for a few reasons. The most common culprits include worn gears or a broken cable in the regulator assembly itself . These cables get flexed every time you open and close the window, and over time, they can snap.
Before you dive into the replacement, do a quick sanity check. There’s about a 36% chance your issue is electrical—like a blown fuse, bad relay, or faulty wiring—rather than a broken regulator . That’s an easy fix, so check those fuses first.
The Swap Process (What the Manual Says)
Here’s the condensed version of the rear window middle glass regulator replacement process :
- Get Access: Remove the rear seat-back and rear trim panel.
- Disconnect: Unplug the connector from the regulator motor.
- Remove: Take out the mounting bolts, detach the cable clips, and pull out the old regulator and motor.
- Grease It Up: Apply multipurpose grease to the sliding surfaces of the new regulator .
- Reinstall: Put the new unit in, reverse the steps.
Bolt Torque Spec: The bolts are 6 x 1.0 mm and need to be torqued to 9.8 N·m (1.0 kgf·m, 7.2 lbf·ft) .
What Owners Are Saying
Some Ridgeline owners have reported rear window motor failures, even on newer 2023 models . One forum user noted that their dealer found a defective harness after a long diagnostic process, followed by a bad rear window motor . It’s worth noting that these issues seem rare overall .
For comparison, some owners have reported tailgate wire harness issues where wires break, causing backup camera and alarm failures . Different part, but similar frustration with cables in the rear of the truck.
A Word of Caution
Safety reminder: Always disconnect the negative battery cable before starting any electrical repair. This prevents accidental short circuits and keeps you safe.
Also, if you’re dealing with a defroster issue on that same glass, the sliding glass itself can be replaced separately—you don’t need to replace the entire rear window assembly for that .
