LS 430 Door Lock Actuator Tutorial
My door lock actuator wasn't working. It failed all of the sudden and I decided to try seeing if a new motor would fix my issue.
And I used this excellent tutorial to pull the door panel / door card off.
If you work on any Japanese made vehicle, Japanese manufacturers don't use a true phillips screw, they use something called JIS or Japanese Industrial Standard specifications. Phillips screws are designed to strip once you reach a certain torque. JIS screws don't, they work in a paradigm that the operators knows what they're doing and the screws should not strip and prioritize contact between the bit and screw - you'll notice that your screw driver will rarely slip out of the screw if you get them lined up right.
So now you're looking at this great door!
There are six torx bit bolts (I used a T30 bit for all of them but some people say they're a mix of T27 and T30 bolts)
And 3 10 mm bolts you'll have to remove. (10 MM on my Toyota?! pure craziness).
You can't see a few of the bolts here but there's:
3 Torx bolts near the door latch
1 torx bolt holding the driver's side lock on
1 torx bolt holding the actuator above
1 torx bolt holding the actuator from below (this is near a metal tab)
There's
2 10 mm bolts holding the window track. The window will need to be up for this procedure. Don't let it come down when the track is loose.
1 10 mm bolt holding the door handle this is kinda buried.
Here's where the bolt that holds the door lock is located
So pull that bit of rubber off (using a trim tool that used on the door) and pull the bolt out:
You should be able to remove the lock - just pull it straight out. And pull the door handle out - just slide it back and pull it out.
The door lock actuator comes out the bottom (disconnect it from the wiring harness first), you'll have to pull a lot of the vapor shield out. You need to pull it below the window guide. Perhaps I'll find a camera person and make a video in the future but I believe in you!
Here are some reference photos of the door lock actuator that I pulled out:
The you'll have to split the bottom case, near where the wiring harness plugs in. Then swap out the old motor for the new one and put the case back together. I don't have soft close doors and I kinda destroyed my case opening it... with a soldering gun. So I had to ziptie it together (because the motor and the gear didn't connect...) but then put the actuator back in. Bolt it in. Secure the window guide track. Reinstall your door handle. And then put your door panel back on and try your remote lock/unlock.

I get a page with 10 menu items. I click on "Door Lock Actuator Repair" and a page loads with a menu list on the left and 5 ad links on the right. How do I get to see the tutorial? I have disabled AdBlocker. I am using windows 10 on a tablet.

Which motors did you get? Are they louder than the originals? Did you replace the entire motor or just the end cap with the brushes? I'm curious because I'll be doing all of mine soon.
