🚗 Dorman 740-478 Front Driver Side Window Regulator: Perfect Fit for BMW Models Review

I bought this window regulator for my car in June. I installed it as soon as it was delivered and have driven my car exactly 4 times since June 10th. Part broke today after 4 uses! I can't find where to claim the guarantee as the service seems to be hidden. Revain gets worse every day when it comes to usability. As for this window regulator, unless you plan on selling or selling the vehicle right away, don't waste your money on it. or if you really enjoy taking your door apart and replacing it…

Before buying this item, I read reviews of Dorman window regulators (in general). I've read some who have found that Dorman has improved their quality and manufacturing process. When I received the product, I removed my old BMW ESC and compared it before installing it. I was pleasantly surprised that the quality was very similar. I removed the motor from the previous assembly and attached it to the new slider/pulley assembly. It's only been a few months, but it's working as expected.

Installed, worked about 2 weeks and broke. I thought I made a mistake installing it so I took it to my mechanic. Checked and said it's installed correctly. They installed an original BMW part for me. I couldn't return it as the return policy only allowed a 4 week window. So I waive the costs for this part, as well as the purchase and installation of a new original part. Plus two hours to install and an hour and a half to test if it broke. It can be said that I am not a very happy tourist…

This part was so weak it weighed much less than the original part I removed from my 525IT. The metal was thinner, and one of the cable guides was bent so badly that it pinched the cable, and the plastic retainer attached to it was pinching the window halfway up. I could probably bend the cable routing, but I felt like I wouldn't have to if it was done right and there was some sort of quality control. Raven is great. No fuss on return and I used my BMW dealer wholesale account and got a real OEM

Make sure you tighten all mounting screws before testing the power (i.e. using the switch to move the bracket up and down move). If you don't do this, the holder will stick to the frame. You do NOT want to flex the frame for the wearer to clear the frame (I'm doing this like an idiot - don't be me). Once the mounting bolts are tightened, the frame becomes a "loaded element" (not sure if that's the correct terminology) and the wearer should release the frame. Otherwise the installation was easy,
