Crown Vic turn signal switch
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
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

Defective Part
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 dont expect much from parts not made in America. Chinese parts are all not reliable.

Good part
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 doesnt function as smoothly as the original.
