DOOR LOCK/ACTUATOR REPLACEMENT
Finally fixed my door lock by replacing the actuator/latch assembly. it's not too hard to do, just follow along and you'll get it no problem. Send a PM to rivum
if you have questions
First, you need to remove the trim pieces.
Start with the door handle bar. You need to pry it away by putting a flathead screwdriver in the slot shown below, and then prying away from there. Work your way around the piece with the screwdriver and it should pop off.
Then you need to unscrew the door handle trim. Unscrew the two screws in the pic below.
Now unscrew the two screws in the door handle bar and remove
Now take off the tweeter from the top of the door. It is attached by tabs, so insert a screwdriver behind the piece and pull it away from the frame. Then disconnect the wire harness.
Next, unscrew the 2 screws from the front of the panel
Now take off the three screws from the back of the panel. You'll see them in the diagram below. they have little caps on them, which need to be removed first. The caps are only the inner circle - pry that away with a flathead screwdriver, and the screws will be exposed. Remove all three.
After that, you will be able to take the trim panel off. Pull the panel away from the door frame from the two sides and the bottom. You will then be able to lift the frame up and away from the top of the door.
Be careful of the wire harnesses that are attached. there will be three connected to the window controls and one that connects the door light. Disconnect all 4 harnesses and you will then be able to fully remove the panel. You will now be left with something that looks like this:
Pull away the plastic from the top left corner. It is attached with some kind of silicone. You don't need to remove it all--only enough to get at the inside of the door at the left side.
The next step is to disconnect the two rods from the lock. You will have to look up inside the door and you'll see where they are connected at the top. Pull away the plastic locking clip from each rod and you should be able to pull the rods out from the place they're attached to.
Now unscrew the actuator/latch assembly from the door frame. (There are 3 bolts).
You should now be able to remove the latch/actuator assembly. Make sure that you disconnect the wire harness from the bottom.
Now you need to open up the plastic housing covering the latch/actuator assembly. There are 3 small screws--two on one side and 1 on the other. Once those are off, the top separate pieces of the housing will come off (one will have to be manouevered around the rods).
You can now disconnect the cables attaching the inside door handle and lock switch. They will have plastic locking clips attaching them--pull that away from the connection and you should be able to remove the cable end.
Now reattach the cables to your new actuator/latch assembly. Close up your door trim and you're all set!
Here's my old, corroded actuator/latch. Yay for Hyundai quality!
