Legacy Actuator: Power Door Lock

Installed on a 2007 gmc envoy. The separation is an exact replacement for the original and works perfectly. The reason for the bad rating is that the actuator doesn't work and doesn't work at all. I've seen others with the same problem in other reviews. I had to use my old one. If they exchange my bad part, I'll give a better rating.

Pros
  • Stock
Cons
  • Damaged

Make sure the recess it goes into isn't corroded.

Item fits as it should and works perfectly. I highly recommend thoroughly cleaning and lubricating the indentation where the plug enters the oil pan. Mine was frozen in there and it took several hours of appropriate air hammer blows to remove the broken part that necessitated this purchase.

Pros
  • Hard wearing finish
Cons
  • I will add later

Fantastic replacement part

These are now hard to find and genuine parts are almost impossible to find. This is a good piece at a good price. Removing the old one was a huge pain but once I have this one it works great. I reused the old drive in this new breaker because I knew the old drive was good, but that just means I have a brand new drive in my spares basket in case the factory drive ever fails.

Pros
  • Best in its niche
Cons
  • Approx

Motor drive did not work properly

The metal circuit breaker looks like it came from the factory and is identical to the one originally supplied. I don't use the electrical connection, it doesn't work. I think most say that. Not sure if it's the drive itself but I took the OEM CV axle out of the original decoupler and fitted the axle to this one, I was going to replace the axle with the new decoupler and it had a size in it, I tried everything until it cracked. I'm not sure if it was a break, but I got the axle off the old one…

Pros
  • Many fit
Cons
  • Some difficulties

Works, but not for long. Cheap internals

I replaced the stock connector on my 2006 Trailblazer during a suspension and engine overhaul. The block seemed to work fine for about a year (the son drove). But when checked in late 2021, the front differential was locked. I have confirmed that the actuator on the gearbox and this shut off actuator are working. I removed the separator case and ripped it open to see what the problem was. It turned out that the shift fork, like some other components, was made of a very soft metal. The assembly…

Pros
  • High marks for support and durability from testers
Cons
  • Not as thick as other options
