What This Window Motor Does
The window lift motor powers the regulator to raise and lower the glass. When it fails, you’ll notice:
-
Slow or uneven window movement
-
Window “auto drop” issues
-
Grinding or clicking inside the door
-
Window stuck in one position
On the Nissan 350Z and Infiniti G35, the long coupe glass adds extra strain—making motor wear common over time.

What is a Window Lift Motor?
- The window lift motor is take the drivers input via a switch and send a power signal to the motor to move the window up or down. The window regulator transfers power from the window motor to the window glass, moving it up or down.
- If you have symptoms like takes multiple presses to roll the window up or down, window speed is slower or faster than usual, clicking from the door when the window rolls up or down, or power window won’t stay up or is crooked, you might need to replace your Old Window Motor.

Easy to install and works just like new.

Fit like a glove and works like a charm. Took about 20 minutes total. The hardest part, taking off the door panel.

Window motor for the G35 Coupe failed, and it needed replacement. Was looking for OEM, but cannot beat the price of this product. It was going to rain, delivered in a timely manner and has been going strong!

Great price, especially if it holds up as long as the OEM part. Noticed some motors on Amazon don’t support the one-touch express raise and lower and others don’t have the reset button in case you have to adjust the limits. This motor has both and comes with instructions on how to perform a reset, if needed. The instruction said the motor was adjust at the factory and shouldn’t need reset. Miine worked correctly right out of the box.

Bottom Line: Works fine in a 350Z but this depends on the car.If you know how to install a window motor to save money, then this is a fine option. Obviously, the installation is dependent on your own skill/enthusiasm, but this fit perfect into the driver side of my 350Z. I think it was almost the exact same dimensions as the original one, and it’s lasted for almost a year now with no major issues. The main quirk is that the window rolls up and down noticeably slower than before, even after a re-install and alignment. This may just be mine, but as long as it works, I have no real complaints for the price.

Picture slightly different from actual device but it matches to the original infinity 2006 G35 lift motor, fully functional. Hopefully it will last for a while.

Better than OEM ones
Had issues with both windows on my 350z where they would go back down after putting them up. Replaced them with OEM ones that cost about $150 each. After about 6 months had the same issue. Decided to go with these ones instead of OEM again. Happy I did. So far I’ve had zero issues with them and I paid less than half the price. They seem to be solidly made, include everything required and have instructions to help install and reprogram them if needed.
