Hi,

I have a 1998 LS with a Driver's door lock problem. The motor inside the actuator is worn (brushes) and inop.
I dissasembled the door, removed the lock assembly from the door, dissasembled the lock and opened the actuator.
I have seen this done on a LX:

and a GS (on this site)

I am trying to accomplish the same thing with an LS.
I ordered the motor (Mabuchi FC 280PT - 22125) and they are not the same. I went as far as opening the motors and
trying to swap brushes (in the problem motor they are almost gone) but no dice. They are not the same. I have scoured
the internet for info, or a motor number (no markings on the case of the problem motor). I know that I am going pretty deep,
but the part is over $300 from lexus (whole latch/lock assembly), and the motor should be around $10. Big difference, I don't mind tooling to fix the
occasional problem that I have with this car.
I should have taken a picture, but didn't think of this until all reassembled.
The differences in the motor are as follows:

The problem motor
connections are soldered, (no biggie)
but the motor has posts to solder to.

The ordered motor
Modular (plug type receptical in motor case that plugs into motor, motor side like an a/c recepticle)

Brushes are different in shape and length

Shaft is thicker in problem motor (More Powerful!)

Problem motor has drive gear pressed on, very difficult to remove, but not impossible.

I believe that the motor itself is fine, and a new set of brushes will fix it, so this is an option.

Any one who has gone this far and found motors or a place to find brushes please reply. Would an R/C shop be able to help?
if the motors are all the same in all 4 doors of the LS, I can get a rear door assembly and strip the motor
out but this is over an hour from my house (boneyard with the only LS around).

Thanks,

Fblonk

 

"kid365" has a '98 that he's parting out, I'm sure he'll give you the door lock actuator for less than thirty bucks.
