Door Lock and Door Handle Removal, Disassembly, and Repair:

After many years of use, the stock Z32 door handles can succumb to wear and tear. For this technical document, I had broken my lock cam preventing me from unlocking my door with the key. The following article was documented on a '91 5spd TT.

Tools:
10mm 1/4" drive socket with extension(s).
10mm open end wrench.
#2 Philips screwdriver.
Needle Nose Pliers.
Flashlight

Parts needed:
Replacement parts are to be determined upon removal and inspection.
Nissan only sells complete door handles which include everything needed. Color matched door handles are roughly $150.oo US dollars each.

* I was able to disassemble a door handle from a spare door I have, and use it's good parts to replace my broken parts. Similarly, a door or door handle from a salvage yard might have everything needed.

Estimated Time Required:
Approximately 2 Hours per door.

Procedure:
1. To gain access to the door handle, follow this article to remove the door panel; ZHome.com Door Panel Removal Tech (see "removing the front speakers" section). Also, It is important to raise the window completely, so reinstall the driver side window controls before proceeding.

2. Remove the 1" diameter grommet just above the latch mechanism (1.). Using the 10mm 1/4" drive socket, carefully remove the 10 mm nut from the door handle. It is necessary to use a thin wall socket to get to this nut properly. This can be tedious and time consuming. A flashlight is a great aid. Take precautions to not let the nut fall off the socket, or the socket fall off the extension.

3. Remove the 10 mm nut accessible by using the open end wrench (2.). This will free up the door handle completely.

4. Very carefully, pull the door handle away from the car while twisting it into the approximate position shown (3.). Continue to twist the door handle (carefully!) and lift the door handle mechanism. Lifting the door handle will free the upper door handle actuating arm (4.) and allow the door handle assembly to be pulled out of the door.

5. Again, very carefully, remove the actuating rods from their white plastic retainers (4.). The retainers should rotate off of the actuating rods. Breaking either of these will effectively ruin any chances of a successful repair of any part of the door handle. The door handle should now be free, other then the wire harness.

Note: The entire handle can be removed by disconnecting the harness at the connecter just forward of the seatbelt return mechanism on cabin side of the door. I chose not to as the harness goes through several plastic retaining clips.

6. Remove the door lock cam by removing the C-Clip (upper yellow dot 5.)

7. Remove the vehicle alarm sensor (large white object) by removing the screw (right dot 6.). When removing the alarm sensor, take caution in not bending the metal tab residing within the alarm (red dot 5.).

8. Remove the door lock tumbler. The lock tumbler is held in place by a large wire spring encompassing the entire barrel of the tumbler (lower yellow dot 5.).

9. Once removed, all that is left is the key hole light switch, and key hole light bezel. Take extreme caution here as the key hole light bezel is usually very fragile. The light bezel is held in place by the small screw (left dot 6.) Using your index finger, push the light bezel out through the back side (where the lock used to reside).

10. There is no need to remove the key hole light switch. Our cars from the factory would sense when the door handle was pulled, and would illuminate the door key hole lights, and the steering column key hole light. After years of use, the switch can fall out of 'alignment' with it's actuating piece of metal ribbon (7.). Use a pair of needle nose pliers to tweak the metal ribbon until it functions properly again.

11. Reassembly of the door handle is in reverse order and with less difficulty as the actuating arms snap easily back into their plastic retainers on the handle, once the handle is set in the position shown (4.).

In review, there are 5 servicable parts of the door handle, repaired, or replaced;
a. the full metal door handle housing seen from the outside, including the sprung door handle
b. the key tumbler
c. the key hole light bezel
d. the key hole light switch
e. the factory alarm sensor

And as an additional note;
The door handle can not be adjusted to prevent rubbing (8.) as there is no mechanism to allow adjustment. Both the door handle, and the door handle housing are made of a very hard cast metal (steel?). I tried manipulating the handle with a various tools without success.
