DIY Door inner handle, lock, cable repair 2001 LS430 (1 of 2)
Not too long ago my driver's side inside door handle stopped working and my rear passenger inner door lock stopped working. These were both pretty easy fixes with OEM parts that I ordered off the Internet for a fraction of the price the dealer wanted to charge me for parts and labor. Hopefully this DIY will help some of you save some $$ and get to know your car better!
I was successful in completing these repairs without damage to my LS430, however, I am not responsible for any damage that may occur by following these steps, please work carefully and slowly especially when removing and replacing trim.
Removing the inner door handle cover
Using a small flat screwdriver that is taped on the end to prevent damage, pry the plastic cover that is located behind the inside door handle away from the door panel. Pry on the side closest to the Manual door lock mechanism. Hinge the cover outward while holding the metal door handle in the open position. The plastic cover should hinge on a tab on the opposite side.
Once the cover is off unscrew the door panel screw.
Removing the window control unit
Using the taped flat screwdriver, pry up on the back edge of the window control unit. Note where the clip is located. The opposite end of the window control unit hinges on a plastic piece, do not pry on that end of the unit.
Also note that the power wire harness and light bulb are connected to the unit, and need to be disconnected before complete removal.
Once the control unit is out of the door, the power harness and light bulb need to be disconnected. After they are disconnected you can set the control unit aside. The door panel screw also needs to be unscrewed at this time.
Removing the door panel
Now all of the screws that secure the door panel to door frame need to be removed. Start with a screw that is hidden underneath the armrest. The remaining three screws are located underneath the rubber skirt just below the passenger cabin door light.
Now that all of the screws are out, the door panel can be lifted up off of the door frame. Before doing this, place something that is almost as high as the lower edge of the door panel nearby. You will need this to prop the door panel on once you have lifted it off of the lip. You cannot completely remove the door panel because the wiring harness for the light, as well as the door cables will be attached to components on the back side of the door panel.
You only have a few inches of room once you left the door panel off of the lip, this is why you need something nearby to prop the door panel on so that you can disconnect the light wiring harness as well as the door cables.
