A Home Mechanic's Guide to the 2003-2014 Nissan Murano Window Motor
Is your Murano's power window stuck, slow, or noisy? Here is what you need to know before replacing the window motor.
- Always check the fuse first before assuming the motor is bad.
- A window motor reset procedure is mandatory after replacement to ensure proper function.
- Aftermarket brands like Dorman offer a reliable, cost-effective alternative to expensive OEM parts.
- Consider replacing the window regulator at the same time as the motor, as they often fail around the same time.
Is Your Nissan Murano Window Motor Failing?
A failing window motor can be a major inconvenience, leaving you exposed to weather or unable to use a drive-thru. For the 2003-2014 Nissan Murano, window motor failure is a common issue as the vehicle ages. Before you assume the motor is dead, always check the simple things first, like the power window fuse. If the fuse is fine, look for these common symptoms:
🎬 Watch this video to learn how to diagnose the motor.- Slow or Sluggish Operation: The window struggles to go up or down, moving much slower than it used to.
- Intermittent Function: The window works sometimes but not others. This can be frustrating and unpredictable.
- Window Gets Stuck: The glass moves part of the way and then stops, requiring multiple presses of the switch to fully open or close.
- Clicking or Grinding Noises: Hearing strange sounds from inside the door when you press the switch often points to a problem with the motor or the regulator it connects to. One common failure point on these vehicles is a plastic internal gear being stripped by a metal one.
- No Movement at All: If you press the switch and hear a faint click but the window doesn't move, the motor has likely failed completely. If you hear nothing, the problem could also be the switch or wiring.
CRITICAL: Window Motor Reset Procedure is Required
Nissan vehicles, including the 2003-2014 Murano, require a reset procedure after the window motor is replaced or the battery is disconnected. If you skip this step, the "auto-up/down" feature will not work, and the window may bounce back down from the top. This can make a brand new motor seem defective.
Basic Reset Steps:
- Turn the ignition ON.
- Open the window completely by holding the switch down.
- Pull the switch UP to close the window completely. Do not let go of the switch.
- Continue holding the switch in the UP position for at least 3-5 seconds after the window is fully closed.
- The motor is now initialized. Test the auto-up/down function. 🎬 Watch a demonstration of this essential window reset trick.
Choosing the Right Aftermarket Window Motor
When shopping for a new aftermarket window motor for your Murano, you'll find several options. While an OEM part from the dealer is available, aftermarket brands offer comparable quality for a much lower price.
- Dorman: This is a widely available and generally trusted aftermarket brand. Many mechanics and DIYers use Dorman parts and find they get the job done reliably. They may occasionally be slightly noisier or faster than the original part, but they are a solid choice for a balance of quality and value.
- Cardone: Another major player in the aftermarket, Cardone offers both new and remanufactured window motors. They have a reputation for providing quality replacement parts that match the fit and function of the original.
- Replacement / Store Brands: These are typically the most budget-friendly options. While they can save you money upfront, their long-term durability can be a gamble. For a part that requires removing the entire door panel to access, spending a little more on a reputable brand like Dorman or Cardone can save you from doing the job twice.
How Much Does a Nissan Murano Window Motor Cost?

Pro Tip: Should You Replace the Window Regulator Too?
The window motor and window regulator are two separate parts that work together. If you hear grinding noises or the window moves unevenly, the cable on the regulator might be failing. Since replacing either part requires taking the door apart, it is often a good idea to replace them as a complete assembly, 🎬 See this walkthrough for replacing the regulator and motor together. especially on an older vehicle. This can prevent you from having to do the same job again in a few months if the other part fails.
Frequently Asked Questions
Can I replace just the window motor myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical skill. It involves removing the door panel, an inner metal plate, and several bolts in a tight space. You will need basic hand tools, a 10mm socket, and trim removal tools. The biggest challenges are supporting the window glass during the repair and aligning everything correctly during reassembly.
Why did my Murano's window motor fail?
Over time, the internal components of the motor simply wear out from use. A common point of failure in some Nissan motors is a plastic gear that gets worn down or stripped by a metal drive gear, causing the motor to stop working. Age and repeated use are the primary causes of failure.
Do I have to perform the reset procedure?
Yes, it is essential. The Murano's Body Control Module (BCM) needs to learn the upper and lower limits of the window travel to operate the auto-up/down and anti-pinch safety features. Without this step, the window will not function correctly.
Is the front window motor the same as the rear one?
No. The motors for the front doors and rear doors are different parts. Additionally, the driver's side and passenger's side motors are often different as well. Always verify that you are purchasing the correct motor for your vehicle's specific year and door location.
