I've installed several door lock actuators now and I've learned several things along the way. I also spoke with some professionals to get some tips and tricks. All of that information is shared in this video. There is definitely a wrong and a right way to install a door lock actuator. I highly suggest you do not purchase an aftermarket actuator. They are known to have issues. Brand new actuators can be very pricey but you have a great option on eBay.

This video is sponsored by Actuators Plus (eBay). They sell OEM actuators with an optional lifetime warranty. All you have to do is return your faulty actuator in their pre-labelled shipping envelope and your lifetime warranty will be activated.

*Actuators Plus did provide the actuator for this installation video free of charge *

Symptoms of a bad actuator:
1. A door will not lock or unlock using your power locks button in your vehicle
2. Your remote will no longer allow you to lock or unlock the doors of your vehicle.
