Crown Vic turn signal switch
March 19, 2017
The part arrived really quick. Price was about 1/3 of what other sellers were charging. Watched your installation video 3 or 4 times and was able to replace the defective switch in 45 minutes. Everything on the lever is working great. Really helps to know where and how to take things apart. I had a couple of minor differences, but otherwise, great video and part.
DYI Saved me hundreds of dollars
June 20, 2017
The turn signal switch I found on line save me hundreds of dollars by doing it myself. The video that was provided made it simple with very little variations. Other than my ignition switch Tumblr was not quite as shown in the video, only because mine was somewhat different but was still easily removed with a little thinking. I was pleasantly surprised with the low price of the quality made part I ordered along with their customer service when I ran into a problem. I sent them pictures of the switch so they could see the situation and they contacted me back and discuss the matter with me. Come to find out it was my fall in overlooking a certain area. Also they warned me to be sure to disconnect the battery which I did. Success, the turn signal and wiper switch worked perfect. A good thing because the rain X on my windshield was starting to not quite work so well after two months without this part. Thank you 1AAuto.com

Installed this and the wipers don’t work unless on highest setting so at the moment not sure if it’s this part or something else
Defective Part
July 6, 2018
Order came on-time. No issue with the processing. However, I spent 3 hours taking everything apart and then another 2 hours to install. After all that, noticed that the flasher button is defective. Keep turning on by itself and even if the car is parked overnight. I noticed this when my car battery was empty. Anyways, I ordered the part from the dealer and reinstalled everything. Planning to return this next week. 1A is a great company, I know that they are not the ones making the parts, but for me it was a very bad experience. Too much time was wasted. I guess, you don't expect much from parts not made in America. Chinese parts are all not reliable.
Great Product
July 7, 2018
This unit is a great product, great price and quick delivery. 1A Auto videos are extremely helpful.
Good part
July 12, 2018
This is a good part overall and I received it exactly as described. The only reason why I gave this 4 stars instead of 5 is because this replacement part doesn't function as smoothly as the original.
August 18, 2018
Had a mix up on order that was my fault called they fixed it for me and had no problem with getting right parts and delivered in time
Highly recommend

Right part, right fit, low price, received it ahead of schedule.
Easy to install thanks to YouTube video. Awesome!
January 10, 2019
My turn signal canceler broke and it was super annoying. I did some research on-line and discovered that the replacement part was available for a reasonable amount through A1. I bought the part and when it arrived, I watched A1's video. Having watched the video, I was able to replace the part easily. I saved around $100.00 in my estimation by replacing the part myself. Good deal and great video!
Right part att he right time
July 28, 2019
The best part about ordering most anything from A1 Auto are the instructional videos. I have a great idea about what I am getting myself into before ordering the part. This alone has saved me hundreds in labor costs by showing me that I can do it myself.
My New Part
September 8, 2019
The switch did what it was designed to do. It went in just as the instruction video. This isn't my first rodeo with 1aauto, and it won't be my last.

Thank you to the 1A Auto team. With the amount of research that you can find, how to do videos, it went super smooth and the products are speechless. Again thank you all very much for your service and time.

Does this also control the brake lights?

This combination switch would not control the brake lights.

February 13, 2019
Hi Ronnie.. that switch has NOTHING to do with brake lights..
February 13, 2019
I do not know how to answer this direct question. I am just Shadetree mechanic. But I do know that the brake pedal has a switch on it that turns on/off the brake light. That signal then goes through the turn signal switch to alternate the designated tail light bulb. Your tail light bulbs have only two filiments. one for running lights (low intensity), or brake/turn (high intensity) At least, that is how the old ones work...

No it does not control the brake lights at all just the front and back blinkers, winshieldwipers and high beams
