I've finally received my new jamb switch and am ready to replace on the driver's side in my '90. However, several months ago, when I began to research this repair, I was told about a floating backplate and a very specific way of replacing the jamb switch so the backplate doesn't fall inside the door.

Unfortunately, for the life of me, I can't find the thread or video that gave me the instructions. Can anyone point me in the right direction?

Thanks,

I took my door panel off I think if you take one screw out and put a longer one in you can switch it out without dropping the backplate+

This works:

Remove the upper screw, leaving the lower one as-is. Replace the upper screw with a longer screw than the original, threading it into the floating nut plate only a few turns. This will keep the nut plate from getting away from you.

Remove the lower screw, and pull the old switch out of the hole as far as the longer screw you just installed will permit.

Use the upper screw to pull the nut plate against the inner surface of the door.

Reinstall the lower screw to secure the bottom of the nut plate to the door.

Remove the longer screw.

Pull the switch the rest of the way out of the door.

Disconnect the harness connector from the old switch. Discard the old switch.

Plug the new switch into the two-pin connector.

Feed the wiring back into the hole in the door, and start the new switch into the hole.

Install the long screw a few turns of thread into the nut plate.

Remove the lower screw.

Complete the insertion of the switch into the door.

Use the upper screw to pull the nut plate against the inner surface of the door.

Install the lower screw.

Remove the upper screw, and replace with the original short screw.

Close the door GENTLY the first time to set the plunger in the new switch to the proper depth.

Grab a cold beverage. You're done.

Live well,

Followed those directions. It worked perfectly, and man did that beverage taste good!

Thanks a million for your help. I really appreciate it. That backplate would have been inside my door if it wasn't for the internet and this forum.

You're most welcome. That procedure is a lot easier than removing the door panel, etc.

Glad it helped, and that everything worked out for you.

Live well,
