2012 Toyota Tundra Power Sliding Rear Window Replacement – Full Repair Breakdown
Replacing a power sliding rear window on a 2012 Toyota Tundra is a detailed process involving interior disassembly, electrical connections, regulator alignment, and precise glass adjustment. Unlike a fixed back window, a power slider must be installed and calibrated correctly to avoid binding, leaks, or premature regulator failure.
Below is a step-by-step overview of how a 2012 Tundra power slider replacement is professionally completed.
Step 1: Interior Panel Access – Dual Clip Entry
This is related to a Crew cab, in which you can lower the back seats to be able to access the back paneling and regulator with ease.
The process begins by carefully accessing the rear interior panel using factory clip points. This allows controlled removal without damaging trim or mounting hardware.
Step 2: Back Panel Removal and Reattachment
Once back seats are lowered and access is established, the full rear panel is removed to expose the power slider assembly, regulator, and wiring harnesses. This allows access the metal covering
Why this matters:
Improper removal often leads to broken clips, rattles, or misaligned panels after reinstallation.
Step 3: Bottom Back Plate Access
The lower back plate is removed to gain access to the bottom portion of the regulator and glass mounting points. After unscrewing the eleven 10mm bolts, there’s a clip to remove in the upper right side, and a tab placement on the lower left. To place back in, slide in the bottom into the tab holder and clip the upper right. The clip that helps hold the plate in place is shown below.
Step 4: Regulator Access Clip Removal
An access clip that holds the metal plate must be removed to allow full movement and safe handling of the regulator assembly. This helps hold it in place with the previous tabon the bottom to make it easier to unscrew the 11 screws and single bolt to access the regulator, etc. Below shows the details on what this looks like. Using any type of pry tool should easily release this single clip.

Step 5: Disconnecting Electrical Components
Before the metal back plate and glass removal, the regulator motor wiring wire is safely disconnected to to remove the back plate entirely. Simply disconnect the wire that provides power to the regulator for the power window using your thumb, then pull. This allows you to pull the regulator access plate away for easy access to the regular and the project itself.
Next, you need to disconnect the rear defrost wires from the broken glass (by pressing your thumb on the tab and pulling gently.)
Step 6: Single Nut Removal
Factory fasteners securing the damaged glass are removed in sequence. These mounting points are critical for proper alignment of the new glass. This final point is what holds the back plate in place. After removing this, you might need to pry on the edges the free the metal back plate from its place. Next, we need to remove all of the broken glass.

Step 7: Removing Broken Glass and Brackets
You will need a 10mm to remove the old broken glass brackets. Once detached, the damaged glass brackets are carefully removed. Once these are removed, we will need to get ready to clean any eccess glass up before we put the new glass in place.+
Step 8: Clearing and Vacuuming Broken Glass
All loose glass fragments are removed from the track using specialty tools and vacuum equipment. This step is critical — even small shards can cause the new glass to bind or derail the regulator, or even possibly cause it to shatter again.
Starting from the top, you basically push the glass down to the sides, making it easier to vacuum all the glass up in the final cleaning process, aside from any final touchups that may be necessary.
Normally, you would want to clear and cleanup any tempered glass for the sole purpose of not hearing it once you open and close a door. Typically the windshield alone is laminated. Most vehicle nowadays have laminated door glass, etc.
Even though this is a back glass and will not typically affect anything since there is no movement to determine any previous breakage and whatnot, it’s always a good habit to have good housekeeping.
Step 9: Replacing the Felt Protector
This piece is usually removed after the back paneling is removed. The felt protector is to ensure smooth glass movement up and down to reduce friction and noise during operation. It also helps to insert the new backglass into place. (FYI: To insert glass into place, it is done from outside and must be done at a tilted angle. It is a tight fit, however, once lowered, can be shifted into its proper place and lowered.
Step 10: Aligning New Glass Brackets Onto the Regulator
The new power slider glass is aligned precisely with the regulator brackets. This is one of the most important steps to ensure proper operation and long-term durability. The bottom of the glass brackets sit on top of the metal regulator sitting positions, allowing for an easier jogb to screw back in the four 10mm scres to lock the glass into place. make sure to not screw all four in completely. Operate the glass as shown below into top position, then bring back down, to insure proper lineup, then tighten completely.
Step 11: Adjusting and Testing the Power Slider
The power sliding rear window is adjusted and tested multiple times to confirm smooth movement, proper sealing, and correct stopping points before fully tightening the 10mms fully.
