2013-2019 Cadillac XTS Power Window Motor: Programming, Part Numbers & Replacement

Symptoms of a Failing Window Motor 🎬 Watch: Signs & Symptoms of a Bad Window Regulator/Motor

When the power window motor in a Cadillac XTS begins to fail, it usually provides several warning signs. Diagnosing the issue correctly can help you determine if the problem is the motor, the regulator, or a simpler electrical issue like a fuse.

• Slow or Sluggish Operation: The window may move up or down much slower than it used to. This can indicate a weak motor that is struggling to move the glass.
• Grinding, Clicking, or Chattering Noises: Unusual sounds from inside the door panel when you press the window switch are a common symptom. A grinding or clicking noise often points to a problem with the regulator's cables or gears, which are part of the assembly.
• Intermittent Function: The window may work sometimes but not others. This could be a sign of a failing motor, a loose electrical connection, or a problem with the wiring that runs between the door and the vehicle body.
• Window Drifts Down: You may find the window has lowered on its own after being parked. This typically points to a failure in the regulator mechanism that can no longer hold the weight of the glass.
• Total Failure: The window doesn't move at all when you press the switch. While this could be a dead motor, it's also important to check the fuse and the window switch itself first.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

As of this writing, there are no specific recalls or Technical Service Bulletins (TSBs) issued by the National Highway Traffic Safety Administration (NHTSA) for the power window motors or regulators on the 2013-2019 Cadillac XTS. Most failures are due to normal wear and tear over time. However, it's always a good practice to check for any recent recalls using your vehicle's specific 17-digit Vehicle Identification Number (VIN).

Buying a Used 2013-2019 XTS Power Window Motor: What to Check

Purchasing a used OEM window motor assembly can be a cost-effective solution, but careful inspection is key to getting a reliable part. Given the electronic complexity, a used original part is often more reliable than a cheap aftermarket alternative.

Crucial: Verify the Connector Pins

The most critical step before buying is to verify the electrical connector on your existing motor. The 2013-2019 XTS used different motor designs that are not interchangeable. You may find motors with 2-pin, 6-pin, or 7-pin connectors. Aftermarket listings for the front passenger side, for example, often specify a 7-pin connector. You must remove your interior door panel to physically inspect your motor's connector before ordering a replacement. Failure to match the pin count will result in a part that won't plug into your vehicle's wiring harness.

Physical Inspection Checklist

• Check the Connector: Look for any signs of corrosion (green or white powder) or bent pins inside the electrical connector.
• Inspect the Assembly: Check the regulator's cables for any fraying or kinks. Look at the plastic guides and pulleys to ensure they aren't cracked or broken.
• Look for Water Damage: Check the motor housing for any signs of rust or water stains. Water intrusion is a common cause of premature motor failure.

Installation and Programming Guide

Replacement Difficulty: 3/5

Replacing the window motor and regulator assembly is a moderately difficult job for a DIYer. It requires removing the interior door panel, which can be tricky due to hidden clips and screws. The entire process typically takes 1.5 to 2.5 hours.

Step-by-Step Overview

1. Disconnect the Battery: Always disconnect the negative battery terminal before starting any electrical work.
2. Remove the Interior Door Panel: 🎬 Watch: How to remove front door panels on a 2018 Cadillac XTS This involves prying off trim pieces and removing several 7mm screws. Be careful with the plastic clips that hold the panel to the door frame.
3. Peel Back the Water Shield: Carefully peel back the foam or plastic water shield to gain access to the inside of the door.
4. Support the Window Glass: Tape the window glass in the fully raised position using strong painter's tape.
5. Unbolt and Remove the Assembly: Disconnect the motor's electrical connector. Unbolt the window regulator assembly from the door frame and carefully maneuver it out through the access holes.
6. Install the New Assembly: Transfer the new motor and regulator assembly into the door and bolt it into place. Reconnect the electrical connector.
7. Test and Program: Reconnect the battery and the window switch. Perform the relearn procedure below before reinstalling the door panel.

Crucial: Window Motor Programming (Relearn Procedure)

This simple procedure teaches the new motor its upper and lower limits, which is necessary for the one-touch and anti-pinch features to function.

1. Turn the ignition to the 'ON' or 'RUN' position (engine off).
2. Using the window switch for the newly installed motor, press and hold the switch down until the window is fully open.
3. Continue holding the switch down for 3-5 seconds after the window is fully open, then release.
4. Now, pull and hold the switch up until the window is fully closed.
5. Do not release the switch. Continue holding the switch up for 3-5 seconds after the window is fully closed.
6. Release the switch. The auto up/down feature should now be restored. Test it to confirm.
