The item I received in the box was not the item pictured. Buyers, If you get the item that does not have the yellow tip with the roller on the end (as pictured on Amazon) it’s the original version that buick put in that keeps failing. Without the roller on the end for the cable to roll over it ends up dragging through the white plastic tip and cutting through the end and failing again and again. Seller, If you are going to picture something please don’t insult my intelligence by trying to ship me inferior products. UPDATE: Why do you continue to sell this product when it is not what is pictured. The one you are shipping is not the updated model. It keeps breaking. IT DOES NOT HAVE THE YELLOW TIP OR PULLEY ON THE END AS YOU HAVE PICTURED. IT JUST DRAGS THROUGH A PLASTIC SLOT UNTIL IT CUTS THROUGH AND FALLS APART! THAT’S WHY THEY REDESIGNED IT. QUIT MISREPRESENTING THIS ITEM!

As with the other 3 I’ve done for the mum, it fit fine, sheet stamping was good, it comes with new screws with threadlocker pre-applied.
Granted, if you have a few more dollars, it’s not a bad idea to swap the motor as well if you notice the window moving slowly even with the engine on.

Bought this to fit the front passenger window on my 2005 Buick Century. It fit as factory and was relatively easy to install (due to the age of the car some of the brittle plastic of the door panel was a little worse for wear, so be careful when removing for the install). Everything lined up correctly and the factory motor installed easily. That said I should have replaced the motor at the same time since it is a little sluggish, but it was before and I was being cheap since it’s an older car. Overall, no complaint about the part and very please with the quality and price.

Exactly like dealer for way less and perfect fit

Loved the Prime shipping except that they dropped it at the neighbors instead of my house which has a large number on the mailbox. Anyway the part went in well and dropping the existing motor I had which was still good was easy as pie. The package included new clips which were mediocre because they kept breaking when I tried to install them prior to replacing the door panel.

No issues. Didn’t need the motor, so this was good replacement.
