Saved myself $200 (At least) by doing the replacement.
That the parts were exactly a match to the parts I was changing. I ended up replacing 3 of my lock actuators on my 2008 Avalanche. The drivers door first and then a month later, on the same day, the 2 back doors went out. I ordered all 3 and 2 days later with the help of their video, I was able to replace all 3 in one day. I was curious that the driver's door, didn't come with the inner latch cable, as did the back doors actuator. The video showed that you swapped the old cable to the new actuator.
