Not only did the awful washboard road in Death Valley cause me to lose a power steering line, the exhaust system and a tire on my ‘82 diesel suburban, but when I went to open the rear door, the button pushed in and fell inside the door. To get the spare out, my wife had to crawl in the back and drag it over our luggage. Later back at camp, I used my makita to take off the door panel and retrieve the push button.

Back at home, I pulled the handle off and discovered the problem, a little diecast potmetal tab had broken. It retains the return spring and centers the rod that extends from the back of the button. The spring and broken piece are shown below the handle:

I rigged up a replacement with plumber’s tape (the metal equivilent of duct tape). If you don’t know, it’s a roll of sheet metal that has a series of pre-punched holes and is used to make pipe hangers and such. A little forming with pliers and a couple pop rivets and it’s done:

While I had the door apart, I wanted to add an interior door lock and latch. Stock, the only way to lock the rear doors is from the outside with a key, the only way to open the door is with exterior handle. This is not ideal, when locking the vehicle, you can just push down all the door locks in the front, but you need the key for the rear doors. We also occasionally sleep in the back when camping and you can’t get out the back, you have to crawl over the front seats. I’ve also had the rear doors swing closed while I was in the back getting something, again having to crawl out the front (a problem if the back is piled high with stuff). While the handle was off I saw how the latch and lock works. The rod on the button pushes against a plate that opens the latch. The lock works by lowering the plate so that the rod passes over it. So, first I determined that the little pull things on for door locks use #10-24 screw threads (at least older gm cars and trucks). Therefore I used some #10-24 all-thread (or “ready-rod”, continuously threaded rod) to make the lock (and latch) pull.

To make the latch pull, I just drilled a hole in the door and the latch plate. I used a nylock nut on the end. While the button on the outside of the door pushes, this interior latch just pulls. The lock knob attaches to the latch by the way of a coupling nut that I cross drilled with a clearance hole (see above). Then it was just a matter of screwing on some lock pulls.

I could have used a more traditional door handle, but this was simple and unobtrusive. It sits nearly flush, so it isn’t likely to interfer cargo.
