HERCOO Power Window Motors Gear Lift Regulator Repair Kit Replacement Compatible with Mazda 3 5 6 CX-7 CX-9 RX8

This window motor gear kit was easy to install once the motor was removed. Saved a lot of money using this kit. Recommend.

Kit arrived in one day. Items delivered matched specifications and pictures on the Amazon listing!Installed the new gear and rubber parts and window opens correctly. My car is a 2012 CX-9.

Be careful opening gear box, tabs that hold it to door panel will break off easily if vehicle is old. Gears fit perfectly into bear box however final drive gear would not slip into socket on regulator and i ended up pushing it out of place and completely unwinding all the drive cables. Finally got it all back together and installed and everything works great. Go ahead and purchase vehicle specific door trim retaining clips I broke the head off nearly all of mine taking panel off.

Both of the front power windows on my wife's 2013 Mazda CX-9 stopped working properly during the last year. The symptoms were the same with both: loud grinding noise when pressing the window control button with minimal movement of the window. If the window would go down, you would have to use your hands to help pull it back up while engaging the button. The local Mazda dealership wanted $500+ to fix one window. For less than $50, and about an hour, I fixed both. There is a design flaw with the motors that Mazda used. Over time, teeth start to break off of the main gear in the motor, causing it to start to slip. And then more teeth break, making it worse. You don't need a new window guide track or a whole new motor, just new gears. This set of gears worked perfectly. Just make sure to reuse the 2 black O-rings from the original large gear.

I don't know if it'll last but judging by how it looks and feels it should last as long as the one from the dealer. Not that the dealer's part is of superior quality as it failed when the car had just 63,000 miles, but the HERCOO kit is inexpensive and it fits and works just like the original. Both of my front windows actuators went out at the same time on my 2013 Mazda CX-9 but thanks to this HERCOO kit they are working just as if they were brand new. Great product, but now I must wait and see how long they'll last.

Compatible para las 4 puertas mazda cx7 2011. Solo tener cuidado en destapar el motor ya que se rompen facilmente donde van los tornillos

Product fixed my issue for only about 2-3 months. Now im back to helping my window up.

This product came exactly as advertised. I was able to install it very easily. Saved my 400 bucks! Thank you very much!

Use the old male gear that fits into the female gear that is fixed on the door. The new one didn't align/fit it was a different pattern. After that it works fine.
