2012 Mercedes Benz E550 Sedan Front Passenger Side Window Regulator TRQ WRA52539

Very good product! Actually it is manufactured better than the original regulator. I have never replaced a regulator before and found it not too difficult. The Video is a little misleading, it says to electrically raise the window prior to starting and tape so it cannot drop back down. If the regulator is broken, it is not possible. The window has to be raised by both hands.

Fits well and works well. Thanks!

Regulator was a perfit fit for the original oem regulator. It's tight but there's just enough space to go through the speaker hole.

Rene Verified purchase

George from Yuma Az Delivery was fast on time. The part fit like the original. Good price and Looks Good like good quality so I think it should last several years in this extreme heat and dusty area. Definitely will continue buying from this company.

I installed it and it worked fine ?? Easy project

Part fit perfectly and the installation video was a great help on getting it donethank you for the great price and quick shipping!

So far it is working fine.

Works great, fits perfectly.

Part was perfect fit, came with hardware and QR code for video. Very impressed.

10 years old, 100,000 miles and the front passenger regulator died.... horrible noises to get it closed for a 300 mile return home trip. 1A is competitive with good quality, accurate vehicle fit and service life. Bought a 1/4 pop riveter and did it myself, again the 1A video helped, tho it was not as easy as it looked. Now working perfectly, and with less than $100 on parts and tools, compare to dealership $800 + . Thanks 1A this is why I am a repeat customer!
