How do you replace door latch on 1987 Pontiac fiero?

Answer 1

There are about ten diferent parts in each door that coulb be a "Latch"

All of them have a similar repair proceedure.

Remove the inner door panel, to do this remove trim around the inside door handle, the is a philips crew hidden under a little trim button. Remove the arm rest, three screws, two acessed from the bottom and one you remove a little rectangel at the top of the handle portion. The sliding door lock thingy slides to the unlocked postiion and is suposed to snap off if you pull on it. There are little grippy tree retainers into the door around front bottom and rear of the door panel, use a trim removal tool to work them out, if you are not carefull the door panel will be damaged. Once it is loose, window down and lift it up and off the door, remember you have door lockswitch wires to deal with once you have access.

The door handle has little sheet metal nuts holding it on and a little rod clip. To change this the window must be up. The normal socet size is 10 mm, the dificulty level 8/10. Special tools are magnet, and 1/4 drive set with "U" joint and several diferent extentions.

The interior door handle is very easy once the door panel is off.

The main latch mech is very dificult, the last one I did I removed the outer door skin for better acess and was still a 10/10 on the pain in the butt scale.

Remove inner door panel as above, remove mirror, remove door handle as above, there are a bunch of plastic screws around the inner side of the door holding the door skin on. Remove. Remove large screws holding it in, fight with the link rod clips, reassemble reverse of dissasembly.

If you can finish the job with out a blood transfusion you did well
