Perfect fit, great how to video
I am not a mechanic, but I know how to follow directions. The video on Youtube gave me perfect step by step directions on how to remove and replace the regulator. After pricing the regulator locally I decided top give 1A my business. The price was right and I received within two or three days. Perfect fit! Thanks for the video and the product. The window now goes up and down. Thanks.

94 Merc drivers window regulator replacement
The product worked just fine (once I got it installed). WATCH the VIDEO before you start this replacement. Then watch it while you do the replacement. There are differences among the car models and years. My Grand Marquis had additional connections to the door inside panel. it had a trunk unlock cabel and a switch to open the fule door. Hint--- I had a big suction cup I used to help remove and replace the window. It worked great. It took me several (4) hours, but I saved about $300 over having my local mechanic do the job.

So far so good. They sent all the bolts and nuts for the window, but I wish they included 3 more for the door handle.

1AWRG00254-Window Regulator and motor
Great Product, easier to install with the instruction of 1A Auto.
April 10, 2018
Made my life easier.
I was pleasantly surprised it fit so perfectly. Installation went easily, without any problems at all. And it had two wires that might be either, for my vehicle, so I didnt have to go looking for the correct wire, just match the one to my car.

Quality, Fits, and Has Bolts
The window regulator for my FORD looked to be of good quality, and exactly fit my door. The accompanying video was a great help, and do note the kit comes with bolts and nuts which apparently werent available when the video was made.

Window Regulator
Exact replacement and easy to install. Great customer service from 1A Auto. I have had to return a part in the past, no questions ask with immediate replacement. Buy with confidence.

replace bad window regulator
Received on time (as expected) and viewed your on-line display of the replacement. Worked good except for the actual rivet replacement (which need to be replaced with proper sized nuts and bolts) and the moving of the glass (which not use to doing) but other than that it was fine.

fast shipping, great price, fit was perfect> installation was easy works as it should. what more could you ask for? A1 will be my go to guy from now on. jim

window regulator
yes it was affordable direct fit easy to install, plus the hard ware was a big help too , step by step instructions video , yes i will consider 1Aauto for all my projects , i would recommend to friends. Its a great product and saved me a lot on money THATs what i liked . One thing 1 of the replacement bolt when installing the new motor , i had to compromise , the new motor the plate for that motor is Flat , where as the original motor plate is raised platform easy to install all 3 bolts, but the new flat plate on the new motor regulator , one of the hole for mounting , doesnt allow space for that 3rd bolt , or it will bind up against the Motor

Replaced this twice
I replace this 17 months ago and hoped I wouldnt have to do it again, but the part failed. I bought the first one from 1A as well as the second one, basically because I appreciate the installation video. The second part looked like it was made by a different manufacture from the first so Im hopefully this one will last. I only gave it 3 stars because it was supposed to have a lifetime warrant (although I did not try to collect on it). Otherwise it works fine and the cost is reasonable.

J just as described and seems to be quality made works better than the factory one did

Good Product Easy Install
Good Window Regulator. Easy install with 1A video. It was short a couple of nuts for the install. Since you have to drill out the rivets and replace them with nuts and bolts.
October 5, 2018
Will this fit my car? Add a vehicle to make sure
Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Does this power window regulator come with screws? or I have to source them by myself?
Hsu N June 1, 2018
As I recall you had to get your own nuts and bolts, but directions tell you what size. I am not a mechanic, but I can follow directions. Easy to remove and install. I watched their video and it worked
M I June 1, 2018
Not including the screws
Kai Yu H June 1, 2018
Mine came with the screws needed all I had to buy was some loctite.
M S August 21, 2018
Mine came with the required bolts and nuts.
Tom J September 26, 2018
Mine came complete with the correct size nuts and bolts.
Tom J November 8, 2018
What size nut and bolts replace the rivets?
Keith B September 4, 2018
Thank you for your question. It all depends on what size bit you use to drill them out, but we do not have exact specs for the nuts and bolts you will have to get.
