        Lock Actuators

        Fit like a glove, works perfect. One problem: had to tweak the door lock pin bar (essentially made the section that intersects with the motor shorter) because somehow the new motor leaves a little more play than OEM. Hard to explain but not a huge problem. Used zip ties to "shorten" the bars effective movement space.

        Works great

        I’ve had this in my car for about a year. Zero issues, I’ve bought several auction site ones. They’ve all broken within a week, or not worked at all.... quality part here

        My door locks again!!

        Finding this thing at my local parts store and online was upwards of $50, so when I saw this at this price I was skeptical. Install wasn't bad and this thing works like a charm. Now if only I can get my darn key fob to work...

        Exactly what I needed!

        My drivers side door wasn’t locking and was making a loud rattle/virbration when I would push the lock or unlock button on my key fob. I installed this my self from watching a video on YouTube. Very self explanatory! Save some money and do it yourself at home with basic tools! Thanks American Muscle you have always pulled through!

        Door Lock Actuator Motor

        Item arrived in good time. Install was easy, no more than 15mins. Clips up a lot easier than the unit I replaced and works as it should! The competitive pricing allowed me to justify an additional purchase to gain free shipping on orders $50 and over, while still remaining below what I would have paid at my local auto parts store!! Would definitely recommend this product to anyone needing to replace your door actuator!

        Great Product!

        Easy installation and it fixed my door lock not working. It was a little tricky to get it into place but that is just because of how the factory one Was located. Overall fixed that old one that broke. Would buy again if my other side actuator goes
