How do you change a backup light bulb on a 1998 Lincoln navigator?
You have to take the inside panel off the tailgate and if you are just changing the bulb you dont even have to take off the entire panel. It helps to have two people to do this, unhook the panel along the bottom and have one person pull out on the panel and have another look inside it and you will see where the bulb goes. You will be able to reach in and change it.
If it is the same as my 2000 Navigator, you have to remove the inside panel of the tail gate, which is held on with hidden clips on the inside of the panel, a $10 tool at most automotive stores will assist in removing the panel. You must also remove the strap that is held on with 2 Philips screws. (it would have been easier for us if Lincoln had installed an access panel).
