Power Window Lift Regulator Motor Gear Repair Kit Set Replacement Compatible with Mazda 3 Sport 5 6 CX-7 CX-9 RX-8 (1 Set - 6 Pcs)

3 of my 4 windows in my 07 speed 3 were broken and would only go down a few inches. Ordered these (could've gotten away with just the largest white gear) and had all 3 split open and swapped within a couple hours yesterday. No need to worry about the tiny little tabs, they will snap immediately. But because the bolts sandwich the two halves together when bolted up the car, they still fit very snuggly without them. Much cheaper than ordering brand new assembly and easy enough to do. Take your time, go slow cracking the gear housing apart, clean up inside, and put back together.

I ordered 2 sets of these gears after seeing a You-Tube video that repaired a window with the same problems I was having. They fixed the problem and saved me hundreds of dollars as I did not need to replace the whole mechanism. Both the driver and passenger windows now go up and down smoothly and quietly. I would recommend that anyone who has a sticking window with a terrible grinding schreech, look into whether these gears will fix the problem.

Justo lo que esperaba de buena calidad

Bought two sets of these after both driver and passenger side side needed assistance via pulling up on the glass to get the window up. This is after the dealership wanted $562 to replace both. If your window rolls down and has troubling getting up without assistance this is what you need. It’s tempting to buy just the big gear that’s cheaper but I found out that one of the smaller gears was worn down also. You will need a 10mm socket (deep socket preferred) a trim tool, a screwdriver, painters tape, and a chair. Watch the numerous YouTube videos before you start. Roll the window all the way up. Tape the window up starting at the bottom of the window going over the window frame and onto the glass on the other side. Two strips are needed. Pop off trim in 3 places, disconnect the motor to the mirror and take out 2 10mm screws and screw behind the door handle. Pry all along the outside of the door with the trim tool. Not gently lift up while slightly pulling the door cover toward you. If you lift straight up it’s hard to get out. Firm but gentle here. Here’s where the chair comes into use. Place the chair close to the dirt but far enough away that it takes the weight of the door assembly and you don’t have to hold it. You can now see the motor. Disconnect the electrical to the motor. Take out the 3 bolts. Now you have the whole window motor assembly out. This next part is tricky and requires you to wear a glove preferably leather and have thin flat blade screwdriver. Lay the motor assembly flat on the table with the thicker side down. Using the screwdriver pry into the plastic at the ears and gently rotate the screwdriver. You will hear a crack, but don’t worry. Now go around the assembly and it will pop open. Take a picture as soon as you open it so you will know how it goes back together. Clean out all the plastic pieces that are floating around otherwise you may be doing this again. Now do everything in reverse. It should take you about 20 - 30 minutes the first time, I’ve done so many now it takes about 7 minutes start to finish. We have 3 Mazda’s. Now pat yourself on the back knowing you just saved yourself at least $175.

This works for a 2012 Mazda CX-9 Touring. The only issue I had is with the spindle piece that fits in the middle of the motor gears did not seat correctly which made it so I could not snap the removable cover back on correctly. I just used the old spindle and got it to snap on. You have to be careful removing the gear covers or you will snap the plastic arms. Honestly, it would be better to just buy the after market motor for $35 and save some time. I will do that next time.

No issues with installation. Was cautioned to be careful while splitting the housing, no problem. Cleaned out the old grease, installing/replacing the gears was simple, applied new grease, put it back together, problem solved. To reset the one touch up and down just roll the window down and hold the button for 5 seconds. Roll the window up and hold for seconds. Mazda should fix this common problem. Probably saved $300 off dealer repair cost unless they would replace the gears only instead of the entire motor assy but I doubt they would.

Our 2010 Mazda CX-7 started having window problems on both the front passenger and driver doors. Youtube is your friend when figuring out how to fix the gears in the window motors. There were broken gear teeth in my window motor which I replaced with parts from the kits that I bought. Both windows work like new again.The passenger door panel has an extra screw that the driver side door does not. So, know that the door panels are not exactly the same. Taking the door panels off was probably the hardest part of the job. You may need replacement clips to put the panels back on for these older cars. Opening the motor housing is the second hardest procedure, but doable with a knife or chisel carefully placed and levered.

I have performed this repair in the past but since it was 5 years ago I watched a few of the well done YouTube videos as a refresher. Got the door disassembled and the motor removed in about 10 min and had all the new gears put into in another 5 min. All that was left was to reattach the motor to the door and snap it all back together. Unfortunately, this is when the problems began. For some reason I could not get it reattached. For some reason, the part that protrudes from the motor housing would not slip into the receiving hole in the door. Tried patiently to gently reseat it but just could not get it to slip in. Eventually pushed harder and ended up knocking the assembly loose from the back side of the door. This then required about 45 min of additional work to fix. Long story short, the cog that came with the new gear kit was too large to fit in the hole. Therefore I had to reopen the motor, dig the old cog out of the trash and reassemble it back into the motor. Having done this, the motor slipped right as it should have the first time. I was very disappointed that I had wasted at least an hour due to the fact that the part did not fit. Hope I can save someone else the trouble.
